Basically, we form a negation in English with the preposition “no/not”.
I have a book. ==> Neg: I have no book.
I am a driver ==> Neg: I am not a driver
Negation with semi-auxiliary “to do”
“cIs it possible to observe negative sentences that carry the writings: don’t/doesn’t or didn’t? “
Yes, that is possible. In English, some verbs, unable to support the preposition no/not itself, are helped by the semi-auxiliary “to do” for doing so! The negation is then formed by the addition of “to do” and the preposition “no/not” (don’t; doesn’t; didn’t)+the remaining sentence.
I have a book. ==> Neg: I don’t (do not) have a book.
I like this cloth ==> Neg: I don’t (do not) like this cloth.
Hope this helps you a lot… Like, share, and comment.0 Commenter
