Etymology: "Annulability" is a plain English compound built from two parts. The first is "annul", which comes from Latin "annullare" (to reduce to nothing), formed from "ad" (to) and "nullus" (none), the same root that gives English "null" and "nullify". The second part is the suffix "-ability", which turns an adjective ending in "-able" into a noun for the quality of being that thing. So "annulability" literally names the condition of being able to be reduced to nothing. The spelling "annullability" with double "l" is an alternative form, following the doubled consonant of "annul" before a suffix. Both spellings are in use, with the single-l form now more common in legal writing.
