Etymology: A certifier is simply someone who certifies, built by adding the agent suffix "-er" to "certify". The suffix itself has a long pedigree. The "-er" ending that English speakers use to turn verbs into names for doers, as in "baker" or "singer", descends from an Old English form "-ere", which in turn traces back through Proto-Germanic to the Latin suffix "-arius", a word-forming element meaning "connected with" or "one who has to do with" something. That Latin ending passed into Old French as "-ier", and Middle English borrowed the French form, so English speakers were working with an ending that had already been reshaped several times before it attached to "certify". The verb "certify" itself came into English from Old French, from Medieval Latin "certificare", meaning "to make certain", built from Latin "certus" ("certain") and "facere" ("to make"). So a certifier is, at root, someone who makes things certain, and the word's whole history is folded into a single suffix on a verb that was itself a borrowing.
