Hi teachers,
Are the following sentences correct?

  1. How many types of sentence are there?

  2. There are four types of sentence: affirmative, negative, interrogative, negative and interrogative.

  3. How many types of conditional are there?

  4. There are four types of conditional.

2

They are all OK grammatically. However, something seems to have gone wrong with the list in #2.

Thank you, Sir Dozy.
What has gone wrong? Could you please tell me?

4

You’ve written ‘interrogative’ twice.

It reads as if your list contains five items, two of which (“negative” and “interrogative”) appear twice. Looking again, I think you mean the fourth item to be “negative and interrogative”. If so, it would theoretically be possible to write:

“There are four types of sentence: affirmative, negative, interrogative, and negative and interrogative.”

but this seems awkward and potentially confusing. I would be inclined to try something like:

“There are four types of sentence: affirmative, negative, interrogative, and negative–interrogative.”

By the way, most claims that there are “four types” of sentence seem to classify these as declarative, interrogative, imperative or exclamatory.
