MW gives me three definitions:
- to persuade to disobedience or disloyalty
- to lead astray usually by persuasion or false promises
- to carry out the physical seduction of : entice to sexual intercourse
According to the OED (Online Etymology Dictionary), the sexual connotation showed up in the 1550s, which should have been well more than a thousand years after the original. Nowadays it seems the only version in use is the third - the last to show up.
I had used the term on a teen lately when I told him that his "friends" were not friends at all, as they had seduced him into doing something that he knew was wrong. He got all 'wait a minute...there's nothing sexual between me and them' on me.
Oy. Just another example of a word that we can't really use anymore. Even though Darth Vader was 'seduced by the dark side'. Folks seem to understand that...or do they? Is that another case of "once you go black...?" :)
