"What is it you like?" "What is it that you like?" "What is it WHICH you like?" "What do you like?"What is the difference in usage AMONG the above four questions which I think have the same meaning? I never heard of the third one. Just put in to cover every possible combination for verification. And I should be saying "AMONG the above" instead of "BETWEEN the above" for more than two items involved, shouldn't I? I suppose I can have any verb in place of "like", such as "have" or "want" and so on, can't I?
"How is it you like it?""How is it that you like it?""How is it WHICH you like it?""How do you like it?"Same questions as for the last lot. Thanks!
