Sense: noun/1
'Advertisement' is the full neutral word and fits formal writing, school essays, and business documents. 'Advert' is shorter, chiefly British, and a little more casual, so it sounds natural in UK speech and newspapers. 'Ad' is even shorter and is the everyday choice in American English, especially online: people talk about pop-up ads, video ads, and ad blockers. 'Commercial' is narrower than the other three. It usually means a paid advert on television or radio, not a poster on a wall or a job notice in a paper. So a British paper may carry a job advert, a website may show an ad, and children may watch a toy commercial between cartoons.
Etymology
The verb 'advert' entered English in the 1400s through Anglo-French from Latin 'advertere', a verb meaning 'to turn toward'. That earlier idea of turning your mind toward something explains the formal verb sense 'notice' or 'refer to'. The noun is much newer: in the mid-1800s, British English began using 'advert' as a shortened form of 'advertisement'. So today's noun and verb share a spelling, but the short noun grew out of a different later development.
