Cleft sentences restructure information to emphasize a specific element. "John broke the window" becomes "It was John who broke the window", same meaning, different focus. For C1-C2 learners, clefts add sophistication to writing and speaking.
"It + be + focused element + that/who + rest"
"What + subject + verb + be + focused element"
"All + subject + verb + be + focused element"
More common than students think. "What I mean is..." and "The thing is..." are everyday pseudo-clefts. Formal it-clefts are common in academic writing and journalism.
