Etymology

It is inherited from Middle English familier,[2] borrowed from Old French familier (“related; friendly”),[3][4] from Latin familiāris (“of a household, domestic; intimate, friendly”),[3][5] a dissimilation of *familiālis, from familia (“household”),[3][5] from famulus “servant”.[6][7] It is related to family.[3][4]

Earliest recorded meaning

Of persons, “on a family footing, extremely friendly, intimate”: about 1340 in the OED,[8] the mid-14th century in Etymonline.[3]

Semantic evolution

“Of or pertaining to one's family or household” is from about 1386,[8] the late 14th century in Etymonline.[3] “Unduly intimate”, too familiar, is from about 1450,[8] and of animals, “tame, domesticated”, from 1483.[8] Of things, “known from long association”, it is from the late 15th century,[3] and “ordinary, usual” from the 1590s.[3] As a noun it meant a close friend from the late 14th century,[3] and a member of a great person's household from the 13th century in Merriam-Webster.[2] A familiar spirit is from the 1560s, and the noun familiar, a demon or spirit that answers one's call, from the 1580s.[3] Johnson in 1755 gave its senses as “domestic” and “affable, not formal”.[9]
