​RELEASE (O.Fr. reles, variant of relais, from relaisser, to release, let go, Lat. relaxare), freedom or deliverance from trouble, pain or sorrow, the freeing or discharge from some obligation or debt, the action of letting go or releasing something fixed or set in position. In law, the term is applied to the discharge of some obligation, by which it is extinguished (see Debt), and to the conveyance of an estate or interest in real or personal property to one who has already some estate or interest therein. For the special form of conveyancing known as “lease and release,” see Conveyancing.
