Etymology

From Late Middle English philacterie, philaterie, filaterie (“amulet; tefilla; balderdash, idle words”), from Late Latin phylacterium (“amulet; reliquary; tefilla”), from Koine Greek φῠλᾰκτήρῐον (phŭlăktḗrĭon, “amulet; tefilla”) (used in the New Testament to translate Hebrew תפילין (“tefillin”)), from Ancient Greek φῠλᾰκτήρῐον (phŭlăktḗrĭon, “fortified outpost, watchman’s post; protection, safeguard”), from φυλακτήρ (phulaktḗr, “guard, watcher”) + -ῐον (-ĭon, suffix forming nouns). Φυλακτήρ (Phulaktḗr) is derived from φυλακ- (phulak-) (the stem of φῠλᾰ́σσω (phŭlắssō, “to guard, watch; to defend, protect”)) + -τήρ (-tḗr, suffix forming masculine agent nouns); and φῠλᾰ́σσω (phŭlắssō) from φῠ́λᾰξ (phŭ́lăx, “guard, sentry”), probably Pre-Greek. The spelling of the Middle English word was probably influenced by Middle French filatiere, philaterie, philatiere, and Old French filatiere, philatiere (“amulet; reliquary; tefilla”) (modern French phylactère), also from phylacterium. Noun sense 1.2 (“fringe which an Israelite was required to wear”) was based on the mistaken assumption that the phylacteries (noun sense 1.1) referred to in Matthew 23:5 of the Bible were the same as the fringes mentioned in Numbers 15:37–39. The modern use of "phylactery" as a term for a lich's artifact originates from Dungeons and Dragons.
