involves

Involves is a verb used to indicate that something includes as a necessary part or consequence, or that someone participates in an activity. It is the third-person singular form of involve and is commonly used to describe what a plan, process, or situation requires or obliges, and who is engaged in it.

Etymology: The word derives from Latin involvere, meaning "to wrap up" or "to envelop," via Old French and Middle English. The sense of surrounding or entailing elements evolved into the modern use of "involve" to indicate inclusion, participation, or commitment.

Usage notes: Involve is transitive and takes a direct object. Examples: "The project involves data collection." "The plan involves several risks." It can also be used with the phrase "to be involved in" to express participation or connection: "She is involved in the planning." The present participle is "involving" and the past participle is "involved."

Nuances: Involve emphasizes inclusion of elements or required steps, while include simply means to contain as part. In legal or formal contexts, involve can also imply implicating someone in an action or matter: "The investigation involved him."
