Yes, thanks! (I still haven't learned the English names for the various brackets, it seems... In my mind, the ones with the straight angles are the "angle" ones.)
And for those learning etymology, parenthesis comes from ancient Greek:
Parenthesis, from "para" (next, beside, near) and "enthesis" (embedd, inline). So, essentialy to "inline near/next to something" (what we do with a parenthetical phrase).
