statis quo

Well, no, statis as a noun is not recorded, so it's an older noun that faded away. Status quo is probably how the phrase started out.

No, French pas is from passus, just like VL *passo is. And the word fathom is related to both past and fast. Je ne sais pas is literally, 'I not know step'. Ne/pas and ne/rien bith being kinds of double negatives.

Qua, as Anu points out today in AWAD, means basically as. So fast as quick, not fixed.

Sorry, my syntax got so snarled up. I was just enjoying myself. Must calm down a little and self-edit before pressing the button.
