The infinitive is a non-finite verb. It does not
agree with any subject, and it does not change to agree with time. So it
remains the same no matter what changes take place. There are two types of
infinitives: 1. Full
Infinitive 2. Bare Infinitive Full
Infinitive The full infinitive has TO in front of the verb: To +
VERB Eg. To sing, to write, to take, to continue, to go The verb
looks like a verb in the present, but it should not be seen that way. It
is actually the base form of the verb. She wants to go home. I tried
to argue against the ban. We decided to sweep the classroom. A verb
in the infinitive should not be put in the past, even when the event is in
the past. These sentences are wrong: We decided to swept the class.
r Last week they decided to continued the game They attempted to ran
away Yesterday. r I was expecting you to replied. r Yesterday, he
asked me to prepared food. r
A bare infinitive is an infinitive
without the TO in front of it. Even without the TO, it is still an
infinitive (not a present). I can see the reason. I didn't go
there. A bare infinitive should not be put in the past. These
sentences are wrong: I didn't forgot the message. She couldn't wrote
the letter because she was busy. He did ate the food last
night. |
