Forms

familiāriter (not comparable)[1] The comparative is familiārius and the superlative familiārissimē.[2]

Etymology

It is from Latin familiāris (“of the household, intimate”) + -ter.[2][3] De Vaan lists familiāris (from Plautus) with familia (“household”) among the derivatives of famulus (“servant”), which he traces to Proto-Italic *famelos (“slave”), comparing Oscan famel (“slave”).[4] Following Rix, he takes the Proto-Italic noun as a back-formation from *famelia (“household”), perhaps ultimately from Proto-Indo-European *dʰh₁-m-elo- (“fundament”).[4]

Earliest recorded meaning

Plautus has it first, in the Rudens: “you handle me too familiarly”; in the Menaechmi a stranger is greeted familiarly.[2][5]

Semantic evolution

Its usual sense is in the manner of a close friend, intimately, on friendly terms: Cicero says nothing is more shameful than to make war on someone with whom one has lived on intimate terms.[5][2] It also means with close knowledge, thoroughly, as when Seneca blames readers who apply themselves to no author closely, and Quintilian speaks of knowing a case intimately.[2][5] Cicero uses it of feeling at home in a friend's villa.[2] The grammarian Velius Longus uses it of what happens habitually, as when ⟨s⟩ commonly passes into ⟨r⟩.[2] Church Latin glosses it in a familiar manner.[6]

  • 81–43 BC – Cicero of intimate friendship.[5][3]
