IELTS pronunciation · Word stress

Word stress that moves in word families (PHOtograph, phoTOgraphy)

Stress in English word families often shifts to different syllables when suffixes are added, fundamentally altering vowel length and vowel reduction. Mastering these shifts ensures your speech maintains a natural English rhythm and remains easy to understand in the IELTS Speaking test.

Technique

How to say it

  1. 1

    Identify the root word and locate its primary stressed syllable, ensuring the vowel is lengthened and pitched slightly higher.

  2. 2

    Notice how adding specific derivational suffixes pushes the primary stress to a different syllable closer to the ending.

  3. 3

    Reduce the previously stressed vowels into weak vowels like /ə/ or /ɪ/ as the stress moves away from them.

  4. 4

    Tap the beat on a table as you speak to feel the rhythmic pulse leap from one syllable to another across the word family.

Watch out

Common mistakes

  • →Keeping the primary stress frozen on the base word's root syllable even after derivational suffixes are attached.
  • →Failing to reduce newly unstressed vowels to /ə/ or /ɪ/, which distorts the natural rhythm of the sentence.
  • →Giving equal emphasis to every syllable in longer derived words rather than highlighting a single primary peak.

In the exam: When discussing complex topics like your career, education, or society in Parts 2 and 3, accurately shifting stress across related words showcases both lexical resource and high-level pronunciation control.

Frequently asked questions

How much does pronunciation count in IELTS Speaking?+

A quarter of your Speaking band. Examiners judge how easy you are to understand and how well you use features like stress, rhythm and intonation, not whether you sound British or American.

Do I need a native accent for Band 8?+

No. An accent is fine at every band. What matters is that individual sounds are clear, stress falls on the right syllables and your intonation helps the listener follow you.

How should I practise these lines?+

Read each line slowly, then at natural speed, then record yourself and compare. Say the sentences in a real answer next, because examiners hear your pronunciation while you think, not while you read.
