How to form the third person singular
Most verbs
Add s to the base form of the verb – sits
Verbs ending in a consonant plus y, change y to i and add es – i.e tries
Verbs ending in o, s ,z, x, ch, and sh, add es – e.g. washes (+ extra syllable when pronounced. )
Note in the negative form, the auxiliary verb doesn’t has the 's' so the main verb doesn’t need an s – e.g. She doesn’t work. The same applies with does in questions.
