Is there any different between "Advert" and "Advertisement" ?


The former is just an abbreviation of the latter. The most common term these days is an 'ad', which is even shorter.

Thanks, Clive!
This one varies by country. In North America, we use "ad" as the abreviation and in the U.K. they use "advert." I think that Australia and New Zealand use "advert" as well.
