Third person singular present tense of advertise; to publicly announce or promote a product, service, or event to attract customers or attention.
From advertise, which derives from Old French 'advertir' (ad- 'to' + vertir 'turn'), originally meaning to warn or direct attention. By the 17th century it specifically meant to announce publicly.
The word 'advertise' originally meant just to turn someone's attention toward something—now we spend trillions of dollars yearly on trying to do this, making advertising one of the most practiced uses of language in human history.
