Every sentence must have a verb. In addition, the verb must agree with the subject. A singular subject requires a singular verb, while a plural subject requires a plural verb.
|am / have / go / see / read …|
|are / have / go / see / read …|
|is/ has / goes / sees / reads …|
- I’m walking to school today.
- You have to study hard.
- Squirrels love to eat nuts.
- Marilyn has to practise dancing.
- Each of them has to make an impromptu speech.
- Both Ali and Lee have a pet at home.
Paired Conjunctions (Correlative Conjunctions):
neither…nor, either … or **
- Neither you nor Lilian has time to learn to play the piano.
- Neither Keith nor I have time to watch football this week.
- Either your parents or Fred is picking you up at the railway station.
- Either Mimi or her children are going to the concert.
** For paired conjunctions, the subject closer to the verb determines whether the verb is singular or plural.
