Freedom is understood as either having the ability to act or change without constraint or to possess the power and resources to fulfill one's purposes unhindered. Freedom is often associated with liberty and autonomy in the sense of "giving oneself one's own laws", and with having rights and the civil liberties with which to exercise them without undue interference by the state. Frequently discussed kinds of political freedom include freedom of assembly, freedom of association, freedom of choice, and freedom of speech.

In one definition, something is "free" if it can change easily and is not constrained in its present state. (Physicists and chemists may use the word in this sense.) Philosophy and religion sometimes associate freedom with free will, without undue or unjust constraints on that will, such as enslavement.
