What are word stress and intonation in English?
Word stress is the extra force, length and pitch given to one syllable in a word, as in PHO-to-graph and pho-TOG-raphy. Intonation is the rise and fall of the voice across a sentence, which signals questions, lists, certainty and emotion. Both carry meaning in English, and getting them wrong often causes more misunderstanding than individual sounds.
What this means in practice
Many Indian languages give syllables more even weight, so English stress and intonation are among the most useful things a phonetics course teaches.
Word stress in practice
- stress can change meaning or word class: PRE-sent (noun) and pre-SENT (verb)
- unstressed syllables often reduce to the schwa /ə/
- dictionaries mark stress with ˈ before the stressed syllable
- word families shift stress: e-CON-omy, e-co-NOM-ic
Sentence stress and rhythm
In English sentences, content words (nouns, main verbs, adjectives) are stressed and grammar words are usually weak. This gives English its stress-timed rhythm: 'I WANT to GO to the MARket.'
Intonation patterns to teach first
- falling tone for statements and wh-questions
- rising tone for yes/no questions
- rise–fall in lists: apples↗, bananas↗ and mangoes↘
- fall–rise for politeness and reservation
Simple ways to practise stress at home
- look up new words in a dictionary and say them with the marked stress
- clap the syllables, loudest on the stressed one
- shadow a short news clip, copying rhythm and pauses
- read a dialogue aloud and mark the stressed words first
- record a one-minute talk and listen for flat or misplaced stress
Practical next steps
- Teach learners to find stress in dictionary entries.
- Clap or tap the syllables of new words.
- Mark stress on the board when presenting vocabulary.
- Practise sentence rhythm with chants.
- Model and drill intonation in short dialogues.
What to keep in mind
Stress patterns differ between British and American English in some words. Be consistent with one model.
Common follow-up questions
What is the schwa sound?
The schwa /ə/ is the short, relaxed vowel in unstressed syllables, as in the first syllable of 'about'. It is the most common vowel sound in English.
Does intonation affect IELTS Speaking?
Yes. Pronunciation is one of the four Speaking criteria, and it includes stress, rhythm and intonation.
How do I find the stressed syllable in a word?
Check a dictionary: the stressed syllable is marked with ˈ before it in the IPA transcription.
