>In common parlance ex means 'example'.

This claim is wrong.

You meant to say "ex." is common, noting the period for the abbreviation. Whereas ex is commonly used (See "ex dividend".) as I did above.

I'm skipping the rest of your reply because it's a waste of time after you loaded up with a spiteful tone -- "you don't know what you're talking about"-- only to be wrong about language and somehow you dispute the Wikipedia article which clearly mentions (anti-)Bolshevik opponents.
