Rather than try and arrive at a particular answer or series of answers, which would be at best misleading, I tend to have recourse to a crib sheet, aka a philosophical dictionary.

Here's one that gives you a down and dirty resume of major philosophers and important technical terms. Different philosophers and different historical periods use some terms differently, but if there is no entry for example for 'ground' it indicates that the term is probably informal and vague, thus - ground: something to rest your case on, especially when tired of carrying it.
