Etymology: "Prefixal" is a plain English formation: the prefix "pre-" joined to the adjective-forming suffix "-al". The prefix "pre-" comes from Latin "prae", meaning "before" or "in front of", and it reached English as a common building block for words about what comes earlier. The suffix "-al" is more layered. It descends from Latin "-alis", which turned nouns into adjectives meaning "pertaining to" or "of the nature of", and it passed into English through Old French "-al" and "-el" forms and then into Middle English as "-al". Because the suffix was already productive in English, speakers could attach it to a prefix-based stem like "prefix" without much fuss. "Prefixal" therefore describes something that belongs to, or works as, a prefix, such as a prefixal morpheme or a prefixal form in a grammar. Its meaning follows directly from its parts, so there is no hidden story to uncover beyond the arithmetic of the two pieces.
