† phylacistn.

Etymology: < classical Latin phylacista jailer (Plautus, though the reading is uncertain) < Byzantine Greek ϕυλακιστής (although apparently recorded later in Greek than in Latin) < ϕυλακ- , stem of ϕυλάσσειν to guard (see phylactery n.) + -ιστής -ist suffix. Compare French †phylaciste (1611 in Cotgrave).It is possible that the Greek word is borrowed from the Latin word, which would thus have been formed < ancient Greek ϕυλακ- , stem of ϕυλάσσειν to guard + classical Latin -ista -ist suffix.
