- advertise (v.)
- early 15c., "to take notice of," from Middle French advertiss-, present participle stem of a(d)vertir "to warn" (12c.), from Latin advertere "turn toward," from ad- "toward" (see ad-) + vertere "to turn" (see versus).
Sense shifted to "to give notice to others, warn" (late 15c.) by influence of advertisement; specific meaning "to call attention to goods for sale, rewards, etc." had emerged by late 18c. Original meaning remains in the verb advert "to give attention to." Related: Advertised; advertising.
