advertise (v.)[advertise 词源字典]: 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.[advertise etymology, advertise origin, 英语词源]

Also used in Middle English in broader senses of "inform, give notice; instruct, to direct; to designate." Related: Certified; certifying. Certified public accountant attested from 1896.
predict (v.): 1620s (implied in predicted), "foretell, prophesy," a back formation from prediction or else from Latin praedicatus, past participle of praedicere "foretell, advise, give notice," from prae "before" (see pre-) + dicere "to say" (see diction). Related: Predicted; predicting.
