Consent refers to the act of giving permission, agreement, or approval for something to happen or for someone to do something. In legal terms, it often refers to the voluntary and informed agreement of an individual to a proposed course of action, especially in relation to medical treatment, sexual activity, or participation in research or other activities that may involve risks or potential harm.

Consent implies that the person giving it has the capacity to understand the nature and consequences of their decision and is not being coerced, deceived, or otherwise manipulated into agreeing to something against their will or without their full understanding.
