it

This pronoun serves as a versatile tool for referring to non-human entities or abstract concepts. While primarily used for objects and animals, it can refer to people in specific contexts, such as when an identity is hidden or during a game, though using it for a known person is generally considered dehumanizing or offensive.

In English grammar, this word frequently functions as a dummy subject, known as an expletive. This allows the speaker to discuss weather, time, or general states of being where no actual agent is performing an action, effectively filling a structural gap required by English sentence patterns.
