Fronting

Any construction in which a part of a sentence is moved to the beginning in order to give it special emphasis.

For example, I have never seen such a mess has a fronted counterpart Never have I seen such a mess, in which the adverb never is fronted. In this case the auxiliary verb have must also be placed before the subject I.

Another example is given below.

I can't watch this movie has a fronted counterpart This movie I can’t watch, in which the direct object this movie is fronted.
