Hello All, In grammar books, it's said that a pseudo-cleft sentence with "what" takes a singular verb if it is in the subject position. However, in BBC's website, I've seen that they made an example sentence like this: "What we need now are actions rather than words". So normally it can also be said this way: "Actions rather than words are what we need now." However in Cambridge University Press, Passages 2 Student Book, it explains that noun clauses as subject always takes a singular verb and gives this example: " What I first realize about people is their eyes." And when we start with "their eyes", we have to say " Their eyes are what I first realize about people". Now it's quite confusing for ESL students. Is there anyone who can enlighten me about this subject? When do we exactly use a plural verb in a cleft sentence with what?
