In a rare show of solidarity, both British English and American English spell advertise with an s in all forms.
To advertise something is to do something to get people’s attention on that object, event, or person. Advertisements are commercials or billboards or print ads with a sole purpose of selling something, even an idea.
This term can be used in a figurative sense. If a girl advertised her presence, she made it abundantly clear she was in the room. Advertised can be used especially if the fact being declared was meant to be hidden.
A person or company which advertises is an advertiser.
