After certain verbs (bid, let, male, need, dare, see hear) we use the infinitive without to as :]
Bid him go there.
Let him sit here.
I made him run.
I heard him cry
I saw him do it.
[Except when they conjugated with do]
The above piece is from my Grammar Book. Here I understood everything except [Except when they conjugated with do]. Could you explain what this mean?
I don't really understand what your book is getting at either. Using 'do' or 'did' doesn't change them (i.e. I would not add the word 'to'):
Let him sit here. --> Do (not) let him sit here.
I made him run. --> I did (not) make him run.
I heard him cry. --> I did (not) hear him cry.
I saw him do it. --> I did (not) see him do it.
(Bid him go there. --> Though it isn't wrong, I would never use this sentence.)
