Description

Used for enclosed spaces, containers, and large geographic areas

IN is one of the most versatile prepositions in English. Primarily, it indicates being inside a container, space, or enclosed area. For time expressions, IN is used for longer periods such as months, years, seasons, centuries, and parts of the day. IN also expresses the means or method used to do something. In British English, you'll commonly hear it used with locations (IN the centre, IN the high street) and periods (IN the holidays, IN the week).
