3° person-singular rule

3° person-singular rule

When we use Present Simple with He, She or It we have to put “s” with the verbs. If there is an auxiliary verb in the sentence then the “s” should go with the auxiliary only.

See the examples bellow:

I work – She works                She doesn’t work          Does she work

You play – He plays     but    He doesn’t play   and    Does he play       

We start – It starts                           it doesn’t start               Does it start

Also:

I do work – She does work

Now,

– If the verbs end with: O, S, SH, CH, Z, X – we have to add “es” with the verbs

I do – She does

You go – He goes

We watch – She watches

– And if the verbs end with: Y after a consonant – we have to replace y for i and add “es” as well

I study – He studies

* Have – Has
