How to Pronounce -s Endings
Regular -s and -es endings sound like /ɪz/ after sibilants such as /s/, /z/, /ʃ/, /ʒ/, /tʃ/ and /dʒ/; /s/ after other voiceless sounds; and /z/ after other voiced sounds.
Created by Denis M., British English teacher.
Your goal: Choose /s/, /z/ or an extra /ɪz/ syllable for regular plurals and he/she/it verb forms, then use the ending in a clear phrase.
Read each explanation, listen to a model and respond aloud at each You say pause. Reveal the model after your attempt, check one point and try again. Finish with the mastery quiz and your own short response.
Keep the learner’s speaking time at each You say pause. Use the brief follow-up, focus feedback on one point and move on. Use the final task to check transfer into the learner’s own words.
Choose your listening model
Choose either accent. Listen, repeat once, then use the word in your own short phrase. Keep the ending and notice when it adds a syllable.
Libby is the British English model and Amanda is the American English model. The same three ending groups apply in both accents. The short vowel in the extra syllable can vary; keep it weak and unstressed.

Compare one cat with two cats, and I play with she plays. The ending helps a listener hear number or who does the action. Its sound changes with the end of the base word.
/s/ · cats
Keep one syllable. Move from /t/ into a short /s/ without adding a vowel.
/z/ · dogs
Keep one syllable. Continue from /g/ into the voiced /z/ sound.
/ɪz/ · buses
Add one weak syllable: bus → buses. Buses has two syllables.
We use /ɪz/ as a teaching label for the extra syllable. Some speakers use a vowel closer to /ə/. Copy the short, unstressed syllable in your chosen model.
cats
Cats, I can see two cats.
dogs
Dogs, the dogs sleep outside.
buses
Buses, two buses stop here.
2. Check the final sound, not the final letter
Say the base word first. If it ends in one of the six sounds in the first row, add the extra syllable. Otherwise, check whether the final sound has voice vibration.
| Base word ends in | Ending | Examples |
|---|---|---|
| /s z ʃ ʒ tʃ dʒ/ | /ɪz/: one extra syllable | bus → buses; wish → wishes; watch → watches |
| Another voiceless sound: /p t k f θ/ | /s/: no extra syllable | cup → cups; cat → cats; book → books |
| A vowel or another voiced consonant | /z/: no extra syllable | play → plays; room → rooms; dog → dogs |
Try it: gently touch your throat. Make a long /s/, then a long /z/. /z/ has voice vibration. Aim for a comfortable contrast; you do not need to force a very loud buzz.
A spelling trap: the written -es does not always add a syllable. Goes is one syllable because go ends in a vowel. Watches adds a syllable because watch ends in /tʃ/.
This is the rule for regular endings. Some noun forms change their base sound too, such as leaf → leaves. Check unfamiliar forms in a dictionary rather than applying the spelling alone.
books
Books, she reads three books a month.
cups
Cups, put the cups on the shelf.
rooms
Rooms, we need two rooms.
plays
Plays, he plays the guitar.
wishes
Wishes, she wishes she could come.
watches
Watches, he watches films at weekends.
3. Carry the ending into a useful phrase
Build two books, she plays and three buses. Keep the ending while you move into the next word. Do not add an “uh” after books or plays.
Now describe a routine: She cooks, reads, and watches the news. Cooks ends in /s/, reads in /z/ and watches in /ɪz/. Each verb refers to she, but the last sound of its base selects the ending.
Transfer to possession
The same sound pattern usually applies to singular possessive ’s: the cat’s bowl has /s/; the dog’s bowl has /z/; the coach’s bag adds /ɪz/. The apostrophe changes the grammatical meaning, not this sound choice. A plural possessive that only adds an apostrophe, such as the dogs’ bowls, keeps the plural pronunciation.
Keep your goal practical: make the word ending understandable inside a smooth phrase. A forced extra syllable can make the word harder to recognise.
A short routine
She cooks, reads, and watches the news.
Repair and explain
Try each repair aloud or in writing before revealing the answer.
A learner says books with two syllables. What should change?
Check the repair
Keep books as one syllable, with /ks/ at the end.
Book ends in voiceless /k/, so add /s/ without an extra vowel.
A learner says every word written with -es has an extra syllable. Test goes and watches.
Check the repair
Goes stays one syllable; watches has two.
Go ends in a vowel and takes /z/. Watch ends in /tʃ/ and takes /ɪz/.
A learner gives all he/she/it verbs the /s/ ending. Test plays.
Check the repair
Plays ends in /z/.
The grammatical job is the same, but play ends in a vowel, so the regular ending is voiced.

Answer key and explanations
- The final sound of the base word Start with the base word’s final sound.
- /s/ Book ends in voiceless /k/, so add /s/.
- /z/ A vowel is voiced, so add /z/.
- Two The ending adds a weak syllable after /tʃ/.
- /s/ Laughs ends in /s/ after the /f/ in laugh.
- /z/ Keys ends in /z/ after the vowel.
- One extra syllable Changes adds one weak syllable after /dʒ/.
- Go ends in a vowel, so goes takes /z/ Goes stays one syllable and ends in /z/.
- buses and wishes Bus ends in /s/ and wish in /ʃ/, so both take /ɪz/.
- /z/ Singular possessive ’s follows the same /z/ pattern here.
Put it into practice
Describe a small room or a person’s routine for 30 seconds. Use at least three plural nouns or he/she/it verbs. Include all three ending groups, then check one word against its model.
Self-check: Does each ending help the listener understand the number or action? Keep books and rooms as one syllable, and watches or buses as two.
Compare with one possible response
My sister has two dogs. She keeps their bowls in the kitchen. She cooks in the evening and watches the news while the dogs wait.
