What is that word?!?

Hey Veeky Forums

I am trying to remember a specific word. It starts with pre-. It means "this argument came first, therefor it can exist without this other argument." Like "A predates B." But it's not predates, preempts, presumes, nor presupposes. It's definitely a verb.

This isn't for school or anything, it's just annoying me that I can't remember

precum.
precedes

Maybe, but it doesn't feel right. Precedes is mostly just chronological

A is a prerequisite for B?

how about just good ol' precede

Prior

Precondition.

>this argument came first, therefor it can exist without this other argument.

Can you explain more what you mean by that? I don't understand what this means.

Precludes

As I remember it, the word is kinda specific for logic. Like, A is true whether or not B is true.
