To seduce is to lure or entice, particularly away from obligations or proper behavior. Often, seducing leads to sex.
Seduce means something close to attract, beguile, tempt, and mislead: a beautiful woman could seduce a dude, and a clever criminal could seduce the same dude into a life of crime. A gorgeous day could seduce you from doing your homework. When you're being seduced, it implies you're being tricked a little bit, often into something that's enticing but not so good. The word is used in a famous line from The Graduate: “Mrs. Robinson, you’re trying to seduce me.”
