The s in the third person singular form
English grammar (See all our English grammar tips)
The s in the third person singular formIn the present tense, regular verbs are conjugated by adding an s in the third person singular:
|I want||We want|
|You want||You want|
|He/She/It wants||They 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)
• The auxiliary verbs be, have and do, which are irregular, are conjugated as follows:
|I am / am not||He is / isn't|
|I have / haven't||He has / hasn't|
|I do / don't||He 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.
