English pronunciation guide

How to pronounce -s endings: /s/, /z/ and /ɪz/

English adds -s to plurals (cats), to verbs (she works) and to possessives (Tom’s). Spelled the same, it is said three ways: /s/, /z/ or /ɪz/. The rule is the same as for -ed endings: look at the last sound of the word, not the last letter.

  • After voiceless sounds

    After /p/, /t/, /k/, /f/ and /θ/. A crisp hiss, no extra syllable.

    cats, books, laughs, months

  • After voiced sounds

    After vowels and voiced consonants such as /b/, /d/, /ɡ/, /v/, /m/, /n/ and /l/. It buzzes.

    dogs, plays, lives, rooms

  • After hissing and hushing sounds

    After /s/, /z/, /ʃ/, /ʒ/, /tʃ/ and /dʒ/. The only case that adds a syllable.

    buses, roses, washes, changes

How to make the sounds

  1. Find the last sound, not the last letter: laugh ends in /f/, so laughs ends in /s/.
  2. After /s/, /z/, /ʃ/, /ʒ/, /tʃ/ or /dʒ/, add a syllable: bus becomes bus-iz, watch becomes watch-iz.
  3. After a voiceless sound, add a short, crisp /s/: cats, stops, books.
  4. Everywhere else, add /z/ and let it buzz: dogs, calls, trees. The buzz is what most learners leave out.

Which ending?

Only the words ending in /ɪz/ gain a syllable. Listen for the buzz in the /z/ words.

  • cats /kæts/
  • dogs /dɑːɡz/
  • buses /ˈbʌsɪz/
  • plays /pleɪz/
  • watches /ˈwɑːtʃɪz/
  • months /mʌnθs/
  • changes /ˈtʃeɪndʒɪz/
  • lives /lɪvz/

Common mistakes

  • /s/ everywhere

    The most common -s mistake. Dogs, calls and trees end in a buzzing /z/, not a hiss.

  • Dropping the ending

    Speakers of Mandarin, Vietnamese and Thai often drop a final -s, so “two book” and “he work” come out. Keep it short, but keep it.

  • An extra syllable after every -es

    Only after hissing and hushing sounds. Makes, likes and hopes are one syllable each.
