What it means
ほしい is an i-adjective used to say that the speaker wants a thing. The desired thing is marked with が, and ほしい normally comes at the end of the sentence. It describes a personal desire for a thing, such as an object, food, or gift. The polite form adds です after ほしい.
Usage note
ほしい is normally used for the speaker's own desire. To describe what another person wants, Japanese generally uses ほしがっている instead of directly saying that personがほしい.
