(1) Temptation to wrong, especially temptation to sexual intercourse. (2) Attraction or charm.
Example:
The company began its campaign of seduction of the smaller firm by inviting its top management to a series of weekends at expensive resorts.
Seduction, with its prefix se-, "aside," means basically "led aside or astray." In Nathaniel Hawthorne's novel The Scarlet Letter, Hester Prynne has to wear a scarlet A, for "adulteress," for all to see after it is revealed that she has been seduced by the Reverend Dimmesdale. Seduction also takes less physical forms. Advertisements constantly try to seduce us (often using sex as a temptation) into buying products we hadn't even known existed.
