c. 1300, purveiaunce, "foresight, foreknowledge, prudence, wisdom" (senses now obsolete), from Anglo-French purveance and directly from Old French porveance, pourveance, from Latin providentia (see providence). From early 14c. as "that which is needed or provided," late 14c. as "act of providing or procuring what is necessary, preliminary arrangement."
abstract suffix of state, from Old English dom "statute, judgment" (see doom (n.)). Originally an independent word, but already active as a suffix in Old English (as in freodom, wisdom). Cognate with German -tum (Old High German tuom). "Jurisdiction," hence "province, state, condition, quality."
