In the hand of a typical <u>it-cleft</u> structure, the focus is on the complement of it-clause.<br/><br/>1. It was <b>David</b> who called.<br/><br/>2. It was <b>impossible</b> to say hello to everyone.<br/><br/>However, in another hand of an <u>anticipatory structure</u>, the focus is at the end because it enables a subject to appear at the end of a clause.<br/><br/>3. It was wrong <b>paying $25 a week</b>.<br/><br/>For sentence 2 & 3, There is a clash in each since<i> it-cleft structure is the same as anticipatory structure.</i><br/><br/>Does the focus is on the adjectives or the rear subjects?<br/><br/>Thank you.
