Seducer
SEDU'CER, noun.
1. One that seduces; one that by temptation or arts, entices another to depart from the path of rectitude and duty; pre-eminently, one that by flattery, promises or falsehood, persuades a female to surrender her chastity. The seducer of a female is little less criminal than the murderer.
2. That which leads astray; that which entices to evil.
He whose firm faith no reason could remove,
Will mest before that soft seducer, love. Dryden.
