remembory
remembory is a word i forgot i knew. it's a thing you once knew and know you knew, but can't quite extract it from its storage.
it's on the tip of your mind's tongue (which is located near your mind's eye).
when the thought is locked in the place between your memory and it being remembered, for a short while (sometimes longer) it's a remembory (the thing) which is trapped in your remembory (the place).
