Technical Communication (CY-301) - Unit 5 Short Notes

How unit 5 is examined

Grammar, errors, vocabulary, pronunciation, syllables, tone and personality; marks sit in Professional Personality and Common Errors (high), then Vocabulary, Pronunciation, Syllables and Tone.

Basics of grammar

<span style="display:inline-block;padding:.16em .6em;border:1.5px solid currentColor;border-radius:999px;font-size:.68em;font-weight:700;letter-spacing:.06em;text-transform:uppercase;opacity:.75">Low weight</span>

Definition. <mark>Grammar is the set of rules that governs how words are formed and combined into correct, meaningful sentences.</mark> Grammatical correctness in technical writing means every sentence follows the rules of syntax, agreement, tense and punctuation, so that it has one exact, unambiguous meaning.

Key points.

1. The eight parts of speech: a noun names a thing (engineer), a pronoun replaces a noun (she), a verb shows action or state (runs), an adjective describes a noun (fast), an adverb modifies a verb, adjective or another adverb (quickly, very), a preposition shows relation (on), a conjunction joins words or clauses (and, but) and an interjection shows sudden feeling (Oh!).
2. Sentence structure is subject + verb + object, and the verb agrees with its subject in number: "The engineer tests the circuit" but "The engineers test the circuit". Sentences are simple, compound (two clauses joined by "but") or complex (with a "because" clause).
3. Tenses place action in time: past ("The team tested the code"), present for facts ("The code runs") and future ("The team will test it").
4. Correctness matters for three reasons. It removes ambiguity, so one sentence has one meaning: "Replace the filter in the pump and clean it" does not say what is cleaned; write "Replace the filter, then clean the pump." It improves readability, since a correct sentence is read once. It builds credibility: "The results is wrong" makes a reader doubt the engineer's care.
5. Errors to avoid, wrong to correct: dangling modifier, "After checking the logs, the bug was found" becomes "After checking the logs, we found the bug"; run-on sentence, "The server crashed we restarted it" becomes "The server crashed, so we restarted it"; tense inconsistency, "She ran the test and records the output" becomes "She ran the test and recorded the output".

Common errors in writing and speaking

<span style="display:inline-block;padding:.16em .6em;border:1.5px solid currentColor;border-radius:999px;font-size:.68em;font-weight:700;letter-spacing:.06em;text-transform:uppercase;opacity:.75">High weight</span>

Definition. <mark>A common error is a repeated mistake in grammar, spelling, punctuation or pronunciation that weakens clarity and the speaker's or writer's professional image.</mark>

Key points.

1. Subject-verb agreement: "The list of items are ready" becomes "The list of items is ready", because the subject is "list", which is singular.
2. Articles: "an European engineer" becomes "a European engineer", because the word starts with the consonant sound /j/. A missing "the": "Sun rises in east" becomes "The sun rises in the east", since unique things take "the"; an extra "the": "The honesty is the best policy" becomes "Honesty is the best policy", since abstract nouns in general take none.
3. Tense: "He opened the file and saves it" becomes "He opened the file and saved it", because a shift in tense wrongly suggests a shift in time.
4. Punctuation: a comma splice joins two sentences with only a comma, "The test failed, we reran it", corrected to "The test failed; we reran it", because a comma cannot join two independent clauses. "The team changed it's plan" becomes "its plan", because it's means it is.
5. Run-on sentences fuse clauses with no joiner: "The test failed we reran it" becomes "The test failed, so we reran it", because the reader cannot see where one idea ends. Dangling modifiers attach to the wrong subject: "Walking to office, the rain started" becomes "While I was walking to office, the rain started", because the rain was not walking.
6. Spelling confusions are words that sound alike: "There report is over their" becomes "Their report is over there" (their is possessive, there is a place); "The heat effected the circuit" becomes "The heat affected the circuit; the effect was drift" (affect is the verb, effect the noun).
7. Mother tongue influence (MTI) carries native sounds into English: "wery" for "very", "eskool" for "school", "tes" for "test".
8. Wrong stress: "comfortable" said com-for-TA-ble instead of COMF-ta-ble; "reCORD" for the noun "REcord". Spelling-based mispronunciation says a word as it is written: "colonel" said as spelt instead of "kernel".
9. Fillers ("um", "like", "you know") sound unprepared.
10. Wrong pauses break a phrase: "I will send / the report" instead of "I will send the report / by Monday".
11. Spoken agreement slips: "He don't know" for "He doesn't know", "The engineers is ready" for "are ready".
12. Speaking fixes: pause silently instead of fillers, slow down, record oneself and check stress in a dictionary.
13. Writing fixes: proofread twice (meaning, then grammar and spelling), read aloud, keep a list of one's repeated errors and get a peer review.

Answer frame. Definition; two headed lists, writing and speaking errors, each with a wrong and corrected example and the reason; develop points 1-6 for writing and 7-11 for speaking; close with points 12-13.

Pitfall: Listing errors without a corrected example loses marks, because the examiner expects each error explained with an example.

Asked: [7 marks] (Nov 2022, Dec 2025) What are the common errors in speaking and writing? Explain. Asked: [7 marks] (Nov 2022, Dec 2025) Explain common grammatical errors in professional communication.

Study of advanced grammar

<span style="display:inline-block;padding:.16em .6em;border:1.5px solid currentColor;border-radius:999px;font-size:.68em;font-weight:700;letter-spacing:.06em;text-transform:uppercase;opacity:.75">Not asked since 2022</span>

Definition. Advanced grammar studies the finer structures of English used for precise, formal writing.

Key points.

1. It covers active and passive voice; technical writing uses the passive for processes ("The sample was heated").
2. It covers reported speech, conditionals, collective-noun agreement and parallel structure.

Vocabulary

<span style="display:inline-block;padding:.16em .6em;border:1.5px solid currentColor;border-radius:999px;font-size:.68em;font-weight:700;letter-spacing:.06em;text-transform:uppercase;opacity:.75">Medium weight</span>

Definition. <mark>Vocabulary is the body of words a person knows and uses; general vocabulary is everyday words with broad meanings, while technical vocabulary is domain-specific terms with precise meanings in a specialised field.</mark>

Key points.

1. General vocabulary keeps letters, speeches and conversation open to everyone.
2. Technical vocabulary prevents misreading in manuals, where one term must mean one thing.
3. More words shift sense by field: "mouse" an animal or an input device; "virus" an illness or malicious code; "stress" worry or force per unit area.
4. Technical terms exclude beginners, so use them for experts and explain them in plain words or a glossary for others.

Answer frame. Define both; draw the table; add examples; close with roles, broad understanding versus exact domain transfer.

Asked: [7 marks] (Nov 2022, Dec 2024) What is the difference between General and Technical vocabulary? How do they differ and what roles do they play in communication?

Pronunciation etiquette

<span style="display:inline-block;padding:.16em .6em;border:1.5px solid currentColor;border-radius:999px;font-size:.68em;font-weight:700;letter-spacing:.06em;text-transform:uppercase;opacity:.75">Medium weight</span>

Definition. <mark>Pronunciation etiquette is the courteous practice of speaking words clearly and correctly, with proper articulation, stress and intonation, so that listeners understand and respect the speaker.</mark>

Key points.

1. Articulation means forming each sound fully, not mumbling.
2. Clarity means a steady, moderate pace and sounding every word ending: "test-ed", not "tes", and "results", not "resul".
3. Word stress puts force on the right syllable, as in PHO-to-graph versus pho-TOG-ra-phy.
4. Intonation, the rise and fall of the voice, carries the speaker's meaning and attitude.
5. Pronounce names and technical terms correctly, asking if unsure; mispronouncing a colleague's name is disrespectful.
6. Tone is the attitude the voice conveys, such as polite, confident or empathetic; a warm, steady tone builds trust while a harsh one causes friction.

Why vocabulary and pronunciation together. Vocabulary supplies the exact word and pronunciation delivers it so the listener recognises it; a precise term said wrongly ("ar-chi-TEC-ture") confuses as much as a vague word said well. Together they give clarity, because the message is understood the first time, and professionalism, because the speaker sounds prepared and earns credibility in meetings, interviews and client calls.

How to improve.

1. Read widely (technical articles, newspapers) and keep a word journal of each new word with its meaning, a sentence and its pronunciation.
2. Listen to good speakers, talks and podcasts, and copy their stress and rhythm.
3. Check the dictionary's phonetic symbols and stress mark (ˈ) for every new word: /ˈælɡərɪðəm/ shows algorithm is stressed on AL.
4. Record oneself reading aloud and compare it with a model speaker to catch errors.

Answer frame. Short note: define, give points 1-5, then tone with point 6. Importance question: define vocabulary and pronunciation etiquette, give the "why together" paragraph, then the four ways to improve.

Asked: [7 marks] (Dec 2023) Write a short note on: i) Pronunciation Etiquette ii) Tone Asked: [7 marks] (Dec 2025) Discuss importance of vocabulary and pronunciation etiquette.

Syllables

<span style="display:inline-block;padding:.16em .6em;border:1.5px solid currentColor;border-radius:999px;font-size:.68em;font-weight:700;letter-spacing:.06em;text-transform:uppercase;opacity:.75">Medium weight</span>

Definition. <mark>A syllable is a single, unbroken unit of speech sound built around one nucleus, usually a vowel sound, with or without surrounding consonants.</mark>

Key points.

1. A syllable has a nucleus (the vowel), an onset (consonants before it) and a coda (consonants after it); in "cat", c is the onset, a the nucleus and t the coda. In com-PU-ter /kəmˈpjuːtə/: com has onset /k/, nucleus /ə/, coda /m/; pu has onset /pj/, nucleus /uː/ and no coda; ter has onset /t/ and nucleus schwa /ə/, with no coda in RP, where the r is not pronounced.
2. By count, words are monosyllabic (cat, byte), disyllabic (wa-ter, da-ta), trisyllabic (com-pu-ter, en-gi-neer, al-go-rithm) or polysyllabic (in-for-ma-tion, e-lec-tri-ci-ty, com-mu-ni-ca-tion, tech-no-lo-gi-cal).
3. The six syllable types are shown below.
4. Syllable rules: divide compound words between their parts (foot-ball); VC/CV splits between two consonants (nap-kin); V/CV splits before a single consonant (ti-ger); VC/V splits after it (cab-in); keep prefixes and suffixes separate (re-play, kind-ness).
5. The nucleus can be a syllabic consonant, as /l/ in "table" and /n/ in "button".
6. Stress falls on a syllable and shifts inside word families: PHO-to, pho-TOG-ra-phy, pho-to-GRAPH-ic; e-LEC-tric, e-lec-TRI-ci-ty. It also separates noun from verb: RE-cord and re-CORD, CON-duct and con-DUCT.
7. Wrong division or stress mispronounces technical terms: "analysis" is a-NAL-y-sis, but dividing it an-a-LY-sis gives a wrong word; "thermometer" is ther-MOM-e-ter, not ther-mo-ME-ter.

Answer frame. Definition and structure; six-type table; division rules with examples; close with stress. For the "examples" question, lead with point 2.

Asked: [7 marks] (Dec 2023) What is syllable in technical communication? What are the different types of syllables? What are the rules of syllables? Discuss. Asked: [7 marks] (Jun 2024) What is a syllable? Write examples of English syllables.

Vowel sounds

<span style="display:inline-block;padding:.16em .6em;border:1.5px solid currentColor;border-radius:999px;font-size:.68em;font-weight:700;letter-spacing:.06em;text-transform:uppercase;opacity:.75">Not asked since 2022</span>

Definition. Vowel sounds are speech sounds made with the mouth open and no blockage of the airflow.

Key points.

1. English has five vowel letters but about twenty vowel sounds (12 pure vowels and 8 diphthongs).
2. Pure vowels keep one quality ("sit", "cup"); diphthongs glide between two ("day", "go").

Consonant sounds

<span style="display:inline-block;padding:.16em .6em;border:1.5px solid currentColor;border-radius:999px;font-size:.68em;font-weight:700;letter-spacing:.06em;text-transform:uppercase;opacity:.75">Not asked since 2022</span>

Definition. Consonant sounds are speech sounds made by blocking or narrowing the airflow in the mouth or throat.

Key points.

1. English has 24 consonant sounds, classified by voicing, place and manner of articulation.
2. Voiced consonants use the vocal cords (b, d, g) and voiceless ones do not (p, t, k).

Tone: rising and falling

<span style="display:inline-block;padding:.16em .6em;border:1.5px solid currentColor;border-radius:999px;font-size:.68em;font-weight:700;letter-spacing:.06em;text-transform:uppercase;opacity:.75">Medium weight</span>

Definition. <mark>Tone, or intonation, is the rise and fall of the voice in speech, and it changes the meaning and attitude of a sentence even when the words stay the same.</mark>

Key points.

1. A falling tone signals a complete thought, so it fits statements ("The report is ready") and WH-questions ("Where is the REport? ↘"). The rise or fall happens on the tonic syllable, the most stressed syllable of the phrase.
2. A rising tone signals that more is expected, so it fits yes/no questions ("Is the report ready?").
3. "Fine." falling is agreement, while "Fine?" rising is doubt.
4. A rising tone softens requests: "Could you send the file? ↗" sounds courteous, while "Send the file. ↘" sounds like an order.
5. A rising tone in a statement sounds unsure, so avoid it when giving facts.
6. Tone is the attitude the voice conveys, flow is the smooth, logical sequence of ideas, and purpose is the aim of the speech; purpose decides tone and flow, all matched to the audience.
7. Tones: polite ("Thank you for waiting"), confident ("Our design meets the load requirement"), authoritative ("Everyone must submit the report by Friday") and empathetic ("I understand this delay is frustrating").
8. Flow uses linking words: "First the data was collected, then it was cleaned, so the model trained faster."
9. Purposes: to inform, neutral and factual ("Server load rose 20 percent this week"); to persuade, confident with a benefit ("This upgrade will cut your downtime"); to instruct, slow and in steps ("First save the file, then click Export"); to motivate, energetic with a shared goal ("We are 80 percent there; one strong week and we launch on time").
10. Audience changes the words: to engineers, "Latency rose to 400 ms because of database lock contention"; to a client, "The app slowed because requests were queuing at the database; we have fixed it."

Answer frame. Comparison: define intonation, draw the table, give paired examples, close with effect on meaning. "Tone, flow and purpose": define each in one line, give the four tones (point 7), flow (point 8), the four purposes with sample delivery (point 9), and close with the expert-versus-lay example (point 10).

Asked: [7 marks] (Jun 2025) What is the difference between rising tone and falling tone in speech and how does each affect the meaning of a sentence? Asked: [7 marks] (Dec 2025) Explain tone, flow and purpose in professional speaking.

Flow in speaking

<span style="display:inline-block;padding:.16em .6em;border:1.5px solid currentColor;border-radius:999px;font-size:.68em;font-weight:700;letter-spacing:.06em;text-transform:uppercase;opacity:.75">Not asked since 2022</span>

Definition. Flow, or fluency, is the smooth, continuous and logical delivery of speech without needless breaks.

Key points.

1. Good flow uses a steady pace, correct pauses at phrase boundaries, few fillers and linking words (first, therefore, finally).

Speaking with a purpose

<span style="display:inline-block;padding:.16em .6em;border:1.5px solid currentColor;border-radius:999px;font-size:.68em;font-weight:700;letter-spacing:.06em;text-transform:uppercase;opacity:.75">Not asked since 2022</span>

Definition. Purposive speaking is speaking with a clear aim, such as to inform, persuade, instruct or motivate.

Key points.

1. The speaker fixes the purpose first, then chooses content, tone and words to suit the audience.
2. A clear opening, body and close keep the speech on its purpose.

Speech and personality

<span style="display:inline-block;padding:.16em .6em;border:1.5px solid currentColor;border-radius:999px;font-size:.68em;font-weight:700;letter-spacing:.06em;text-transform:uppercase;opacity:.75">Not asked since 2022</span>

Definition. <mark>Speech is the mirror of personality: how a person speaks reveals confidence, knowledge, character and charisma.</mark>

Key points.

1. Speech is the first impression: listeners judge competence within a few sentences.
2. Firm endings project confidence: "We will deliver on Friday" sounds sure; "I think maybe Friday, um" suggests doubt.
3. A wide, correct vocabulary shows knowledge and precise thinking: "The system is unreliable under load" is sharper than "The system is bad".
4. Voice modulation shows charisma: varied pitch avoids monotony and controlled volume suits the room.
5. Clarity and correct grammar show an organised mind and give the speaker credibility.
6. Courteous words and a warm tone build rapport.

Answer frame. Definition; tree; points 1-6; close: improving speech improves perceived personality.

Professional personality attributes

<span style="display:inline-block;padding:.16em .6em;border:1.5px solid currentColor;border-radius:999px;font-size:.68em;font-weight:700;letter-spacing:.06em;text-transform:uppercase;opacity:.75">High weight</span>

Definition. <mark>Professional personality is the combination of qualities, attitudes and behaviours that make a person trusted, effective and employable at work.</mark>

Key points.

1. Integrity means staying honest under pressure, such as reporting a billing error.
2. Punctuality and reliability mean meeting deadlines, such as delivering the module on the promised date.
3. Accountability means owning mistakes, such as admitting a wrong test result and fixing it.
4. Emotional intelligence is managing one's own and others' feelings, such as calming a stressed teammate.
5. Communication competence is speaking, writing and listening clearly, such as a clear status email.
6. Adaptability means adjusting to new tasks and technology, such as switching to a new framework mid-project.
7. Confidence with humility, such as presenting one's design to the client, wins bigger roles.
8. A proactive, problem-solving mindset offers solutions unasked, such as fixing a bug found by chance.
9. Continuous learning, such as learning a new tool before being asked, protects employability.

Role in career success.

1. Hiring: interviewers judge communication, confidence and integrity as much as marks, so these attributes win the offer.
2. Appraisal: reliability and accountability show in delivered work, which earns a high rating.
3. Promotion: a proactive learner who takes on harder tasks is promoted ahead of one who only does the assigned work.
4. Selection for leadership: emotional intelligence and communication make a person trusted to guide others.
5. Example: a graduate engineer who delivers on time, admits and fixes a bug, and learns cloud deployment unasked is rated highly, promoted to senior engineer and then made module lead. <mark>Reliability leads to responsibility, emotional intelligence leads to leadership, and continuous learning leads to employability.</mark>

Communication and relationships.

1. Listening: active listening (full attention, paraphrasing) makes colleagues feel heard and prevents mistakes.
2. Speaking and writing: clear, polite speech and well-structured emails build trust and a reliable record.
3. Non-verbal skills (eye contact, open posture) and tactful feedback build rapport and resolve problems early.
4. Transparency: sharing progress, problems and data openly with colleagues and seniors builds trust; telling the manager early that a module will slip two days lets the plan change instead of failing.
5. Conflict resolution and team synergy: two engineers disagreed over a deadline; one listened, restated the other's concern and proposed a shared plan, so the conflict ended and the team worked as one.
6. Career advancement and leadership: people who explain ideas clearly and present well are noticed; the engineer who ran clear client demos was made team lead.

1. Structure: audience analysis decides depth; a hook (question, fact or story) opens; three to five signposted points form the body; the close summarises with a call to action.
2. Visual aids (slides, charts, handouts, demos): about six short bullets per slide in 24 pt or larger, never read aloud.
3. Eye contact goes to different listeners, not the screen.
4. Body language: upright posture, open gestures, a natural smile, no fidgeting.
5. Pace and voice mean a moderate speed (about 120-150 words a minute), varied pitch and short pauses after key points.
6. Keep to the time slot; repeat each question and answer it briefly.

1. Preparation: rehearsing aloud against a timer is the strongest cure.
2. Deep breathing: slow breaths (in for four counts, out for four) calm the heartbeat and steady the voice.
3. Visualisation: imagining success replaces fear with confidence.
4. Arriving early to check equipment removes surprises.
5. Audience connection: eye contact with friendly faces and an opening question.
6. Treat nervousness as excitement; it makes delivery lively.
