Present Tense - Third Person
English Grammar Rules
Normally in the present tense we add S to the end of the verb in the 3rd person (He, She, It).
- He speaks three languages.
- She drinks coffee every morning.
- My dog hates my cat.
Irregular verbs in English in the present tense follow very simple rules. The only change that is made to these verbs is in the third person – for He, She or It.
1. If the verb ends in SS, X, CH, SH or the letter O, we add + ES in the third person.
- A mechanic fixes cars.
- She watches soap operas every afternoon.
- He kisses his wife before he goes to work.
2. If the verb ends in a Consonant + Y, we remove the Y and + IES in the third person.
- Isabel studies every night.
- The baby cries all the time.
- He denies all responsibility.
To form the negative we use the auxiliary do not. Again, the only variation occurs in the 3rd person where we use does not.
|I talk||I do not talk|
|She talks||She does not talk|
|You sleep||You do not sleep|
|He sleeps||He does not sleep|
|Carol studies||Carol does not study|
|We study||We do not study|
In the negative, the main verb is always in the bare infinitive (without TO). It doesn't change for the third person. We don't put an S on the end of the verb in the negative form. In the examples above - talk, sleep and study do not change in the 3rd person.
- He speaks Italian
He doesn't speak Italian.
Remember: Do not can be abbreviated to Don't and Does not can be abbreviated to Doesn't.
