Lesson 24: Pronunciation: Word Stress
put the stress on the right syllable so longer words are understood instantly.
Why this matters
English is a stress-timed language: every multi-syllable word has one strong syllable. Vietnamese is syllable-timed (each syllable equal), so Vietnamese speakers often stress the wrong syllable ("PHO-to-graph-y" vs "pho-TOG-ra-phy"), which makes words hard to recognise — a direct hit on Pronunciation.
The Tip/Trick
Learn the stressed syllable WITH the word — mark it with a CAPITAL. Clap on the strong syllable as you say it.
- Before (flat/wrong stress): "com-FOR-table", "PHO-to-graph-er", "de-VE-lop-ment" said evenly.
- After: "COMF-ta-ble", "pho-TOG-ra-pher", "de-VE-lop-ment" — one clear strong beat.
Useful patterns: words ending in -tion/-sion stress the syllable before it (educA-tion, decI-sion); -ity → stress before (responsiBI-lity); -graphy/-ography → "-OG-" (geOG-raphy).
Grammar/Sound Focus — Stress shift in word families (noun/verb)
Rule: some words change stress by part of speech: REcord (noun) vs reCORD (verb); PREsent (noun) vs preSENT (verb). Reference: section 7 (Word stress).
- "I'd like to preSENT my PREsent (gift)." (verb vs noun)
- "They proDUCE good PROduce." (verb vs noun)
- "I keep a REcord, so I can reCORD my progress."
Vocabulary Cluster — High-frequency words to stress correctly
Add to under "Pronunciation: word stress" (mark the CAPITAL syllable):
- comF-ortable, INT-eresting, VEG-etable (3 syllables, not 4)
- phoTOG-raphy, phoTOG-rapher, geOG-raphy, eCON-omy
- ecoNOM-ic, sciENT-ific, neceSSAR-y → NEC-essary (stress first)
- deVEL-opment, enVIR-onment, opporTUN-ity, respon-siBIL-ity
- preFER, suGGEST, deCIDE (verbs stress the 2nd syllable)
Answer Outline (drill, not a topic answer)
- Pick 8 words above. For each: clap the strong syllable, say it 3×, then put it in a sentence.
Model Answers: 5.0 vs 7.0
Question: What do you find interesting about your city's development?
Band 5.0 (mis-stressed, hard to follow): "My city has good de-ve-LOP-ment and the e-co-NO-my is INT-er-est-ing and com-FOR-table for live."
Band 7.0 (clear stress): "My city's deVEL-opment has been impressive — the eCON-omy is booming, and it's become a really COMF-table place to live. What I find INT-eresting is how much the enVIR-onment has improved alongside that growth."
What changed:
- Stress lands on the correct syllable, so every word is recognisable.
- Reduced unstressed syllables ("COMF-table", "INT-resting") sound natural.
- Equal stress on every syllable (syllable-timed habit) → commit to ONE strong beat per word.
- Stressing the last syllable of long words ("developMENT") → usually wrong; check the pattern.
- Adding an extra syllable to "comfortable/vegetable/interesting" → these are 3-syllable words.
Your Turn (Record)
Task: (a) Record the 8 chosen words, then (b) a 1-minute talk on "a change in your city" deliberately using deVEL-opment, eCON-omy, enVIR-onment, opporTUN-ity. ⏱ ~5 min. Listen back for the strong beat in each.
Your turn — record & get scored
Part 2- Speak for 1–2 minutes practising this lesson’s skill.
Self-Check + Spaced Review
Done when:
- Each target word has one clear stressed syllable.
- I reduced "comfortable/interesting/vegetable" to 3 syllables.
- I used 4 stressed words correctly inside sentences.
Spaced review:
- From Lesson 06: keep final consonants clear while stressing syllables.
- From Lesson 08: weaken the small words around the stressed beats.
