Dummy pronoun

A dummy pronoun, also known as an expletive pronoun, is a deictic pronoun that fulfills a syntactical requirement without providing a contextually explicit meaning of its referent. As such, it is an example of exophora.

Dummy pronouns are used in many Germanic languages, including German and English. Pronoun-dropping languages such as Spanish, Portuguese, Chinese, and Turkish do not require dummy pronouns.

A dummy pronoun is used when a particular verb argument (or preposition) is nonexistent (it could also be unknown, irrelevant, already understood, or otherwise "not to be spoken of directly") but when a reference to the argument (a pronoun) is nevertheless syntactically required. For example, in the phrase "It is obvious that the violence will continue", it is a dummy pronoun, not referring to any agent. Unlike a regular pronoun of English, it cannot be replaced by any noun phrase.

The term dummy pronoun refers to the function of a word in a particular sentence, not a property of individual words. For example, it in the example from the previous paragraph is a dummy pronoun, but it in the sentence "I bought a sandwich and ate it" is a referential pronoun (referring to the sandwich).
