Emily Dickinson Lexicon

PROM'IS-ER, n.

One who promises; one who engages, assures, stipulates or covenants. Fear, says Dryden, is a great promiser. We may say that hope is a very liberal promiser. The import of a promise, when disputed, is not to be determined by the sense of the promiser, not by the expectations of the promise. – Paley. Encyc. Note. In law language, promisor is used, but without a necessity or advantage.
