- Rule 1: When the pronunciation of a word ends with the sounds: /p/, /k/, /t/, /f/,/θ/, the suffixes "s" and "es" are pronounced as /s/

- Rule 2: When the pronunciation of a word ends with the sounds /s/, /z/, /∫/, /t∫/, /dʒ/, /ʒ/, the suffixes “s” and “es” are pronounced as /iz/
For example: watches (/ˈwɒtʃɪz/), boxes(/bɒks/), dances (/ˈdænsɪz/),…

For example: plays (/ˈpleiz/), learns (/lɜːrnz/),dogs(/dɒɡz/),…
Pronounced as /s/ when the word ends with the phonemes /p/, /k/, /t/, /f/, /θ/
For words ending in: -p, -k, -t, -f, -th with corresponding pronunciations of voiceless sounds /p/, /k/, /t/, /f/, /θ/, the suffixes "s'', "es" will be pronounced as /s/.
Here are some examples:

To distinguish and pronounce correctly words ending in -sh, -ce, -s, -ss, -z, -ge, -ch, -x, apply the following rule:

Special case of the pronunciation rule s, es
– Case 1: In English, when adding the suffix s or es to words, pronunciation of “s” and “es” will depend entirely on the transcription of the last syllable in the word, not on the last letter of the word (the letter before the 2 suffixes "s" and "es").
Therefore, you need to remember this rule carefully, otherwise you will pronounce it wrong. ETEST English for Study Abroad will give some examples for this special case to help you understand better:
– The verb “use” ends in the vowel e, but the pronunciation is /juːz/
=> When conjugated in the 3rd person singular, adding the suffix “s” will become “uses” and pronounced as /juːziz/.
– The noun “house” ends in the vowel e, but the pronunciation is /haʊs/
=> In the plural form, adding the suffix “s” will make it “houses” and pronounced as /ˈhaʊzɪz/.
– Case 2: In the possessive form ('s), the contraction of is ('s) and has('s), the suffix “s” is pronounced /s/.
