The s in the third person singular form

In the present tense, regular verbs are conjugated by adding an s in the third person singular:
I wantWe want
You wantYou want
He/She/It wantsThey want


I always wear blue jeans, and my sister always wears skirts.

Verbs ending in 'ss' 'ch' 'sh' or 'x' add 'es' to the end of the verb:
Luna washes her hair with a special herbal shampoo. (to wash)
The priest blesses his wine. (to bless)
Susie relaxes every day after lunch. (to relax)

Note:

•  The auxiliary verbs be, have and do, which are irregular, are conjugated as follows:

I am / am notHe is / isn't
I have / haven'tHe has / hasn't
I do / don'tHe does / doesn't

•  The other auxiliary verbs, called modal verbs (will, must, may, would, etc.), have only one form therefore do not need an s in the third person singular:
She must come.
He should be here by now.
