Unilateral

Unilateral refers to something that is done, exists, or affects only one side. It is a term used in various fields such as medicine, law, politics, and biology.

Medicine

In medicine, unilateral refers to something that occurs on, or affects only one side of the body. For example, a unilateral headache affects only one side of the head. Unilateral conditions can be contrasted with bilateral conditions, which affect both sides of the body.

Law

In law, unilateral refers to an action or decision made by one party without the agreement or participation of other parties involved. For example, a unilateral contract is a contract in which only one party makes a promise or undertakes a performance.

Politics

In politics, unilateral refers to actions taken by one nation without the agreement or cooperation of other nations. For example, a unilateral sanction is a punitive measure imposed by one country on another without the involvement or approval of other countries.

Biology

In biology, unilateral refers to structures or processes that occur on or affect only one side of an organism. For example, unilateral flowers are flowers that face in one direction.
