Amicorum

Amicorum is a Latin genitive plural form of the noun amicus, meaning friend. In Latin, amicus belongs to the second declension, and its genitive plural is amicorum, translating as “of the friends” or “of friends.” The form is commonly encountered in phrases showing possession, affiliation, or association.

In grammatical terms, amicorum is used after a noun to indicate that something belongs to or relates to multiple friends. For example, libri amicorum means “the books of friends” or “the friends’ books.” Another common construction is collegium amicorum, translated as “the circle (or fellowship) of friends.” Because amicus has both a nominative plural form amici and a genitive singular form amici, the form amicorum is unambiguous as genitive plural.

Usage and context: amicorum appears across Classical and Late Latin texts, especially in inscriptions, dedications, and literary expressions that describe possession or social relations among a group. It is a typical tool for compactly expressing “of the friends” without repeating a noun.

In modern Latin studies, amicorum is treated as part of standard Latin grammar rather than as a standalone lexical item. It is often encountered in discussions of genitive plural formation or in the analysis of Latin titles and inscriptions.
