Forms

amīcus m (genitive amīcī, feminine amīca); second declension[1]

Etymology

It is from Latin amō (“to love”) + -īcus; the adjective “friendly” is the original use.[2][3] De Vaan suggests that the suffix -īcus may come from an instrumental in *-ih₁ with *-ko-, as in pudīcus and mendīcus.[2][1] The verb is inherited from Proto-Italic *ama- (“to take, hold”), inherited from Proto-Indo-European *h₃mh₃- (“to take hold of”), the meaning having developed from taking someone's hand to regarding as a friend.[2] An old form ⟨amecus⟩ is reported by Festus.[3][4]

Earliest recorded meaning

De Vaan dates the noun from Naevius and the adjective from Plautus.[2] Köbler dates Naevius c. 235–200 BC.[5]

Semantic evolution

As a noun it was a personal friend and also a lover.[3] In public life it was a political supporter, and in the plural a ruler's retinue, his courtiers and counsellors, amīcus populī Rōmānī was a title given to foreign kings and peoples.[3] A philosopher's amīcī were his followers.[3] The adjective meant friendly or well-disposed, politically supportive, loyal and dear.[3] Döderlein notes that amīcus implies a calm affection returned by the other, unlike amāns and amātor.[6]

In medieval Latin an amīcus was a freeman who had commended himself to a lord, and the amīcī rēgis were the great men around a king.[7] It survives in Italian amico, Spanish amigo and French ami.[1]
