Wiktionary says "after all" is a prepositional phrase. It shows these three words: denique, demum, tandem
The English-Latin dictionary I have says it's an adverbial phrase. It shows these other three words: tamen, quamquam and saltem.
The problem is that I think I can literally translate "after all" as "post omnia" into Latin, like this example:
I'm ok after all I've been through
because those translations don't seem to fit in Latin.
What would be the better word?
