[ prom-uh-sawr, prom-uh-sawr ]

/ ˌprɒm əˈsɔr, ˈprɒm əˌsɔr /

a person who makes a promise.

Origin of promisor

First recorded in 1840–50; promise + -or²

It is only in the degree of power possessed by the promisor over the event.

The Common Law |Oliver Wendell Holmes, Jr.
Such is always the case if the condition of a promise lies within the control of the promisor's own will.

The Common Law |Oliver Wendell Holmes, Jr.
For one thing we do not recognize as legally enforceable all intentional promises intended to be binding upon the promisor.

An Introduction to the Philosophy of Law |Roscoe Pound
Not literally compel even in that case, however, but put the promisor in prison unless he will convey.

The Common Law |Oliver Wendell Holmes, Jr.

Whether a promisor is a surety, a guarantor, or an indorser depends upon the particular kind of a contract made.
