edify: [14] As its close relative edifice [14] suggests, edify has to do literally with ‘building’. And in fact its underlying etymological sense is ‘building a hearth’. That was the original sense of Latin aedis. Gradually, though, it was extended, in a familiar metaphorical transition, from ‘hearth’ to ‘home’ and ‘dwelling’. Addition of a verbal element related to facere ‘make’ produced aedificāre ‘build a house’, or simply ‘build’.

Its figurative application to ‘instruction’ or ‘enlightenment’ took place in Latin, and has no doubt been reinforced in English (which acquired the word from Old French edifier) by its accidental similarity to educate.
