Itclefts

ItClefts, or it-cleft constructions, are a syntactic device used in English and several other languages to place emphasis on a particular constituent by splitting the sentence into an introductory it clause and a following that-clause. The canonical form presents the focused element in a position of prominence, while the rest of the sentence is presented as the comment.

The typical English pattern is It is/was [X] that [Y]. Here, the word it acts as a dummy subject; [X] is the focused constituent, such as a noun phrase, prepositional phrase, or clause, and [Y] is the remainder of the sentence introduced by that. In informal speech, the word that can sometimes be omitted, yielding forms like It is John I saw at the store. The construction can also orient contrast or specify information in contexts where the speaker wants to highlight a particular item or cause.

Function and usage: It-clefts serve information-structure and focus-marking purposes. They are common in discourse where highlighting a specific element improves clarity, resolves potential ambiguity, or contrasts alternatives. They often interact with prosody, as the focused element receives strong stress.

Cross-linguistic and theoretical notes: It-clefts occur in various languages, though the exact realization varies; some languages use different auxiliary or extraposition strategies. Linguists distinguish it-clefts from related forms such as wh-clefts (What X is Y) and pseudo-clefts, which achieve focus through different syntactic routes. In theoretical approaches, it-clefts are analyzed in terms of focus, topic, and information structure, with attention to how the fronted constituent and the after-clause contribute to the discourse meaning.
