Pronunciation

  • Classical: [ˈkoː.mɪs][1]
  • Ecclesiastical: [ˈkɔː.mis][1]

Forms

cōmis (neuter cōme, comparative cōmior, superlative cōmissimus, adverb cōmiter); third-declension two-termination adjective[1] The Duenos inscription has the archaic spelling cosmis.[2][1]

Etymology

The origin is uncertain.[2][3][4] It is perhaps inherited from Proto-Italic *kom-smi-, from a root Proto-Indo-European *smi- (“to smile”), so that it would first have meant smiling along with someone.[2][5] Eichner derives the archaic form ⟨cosmis⟩ from a verb *ko-smei- (“to contract the face to a smile”).[2] Cognate with Sanskrit स्मयते (smáyate, “smiles”), Ancient Greek φιλομμειδής (philommeidḗs, “who likes to laugh”) and Latvian smiêt (“to laugh”).[2][5] Varro derived the adverb cōmiter from Ancient Greek κῶμος (kômos, “revel”), the source of cōmissātiō.[6][3]

Earliest recorded meaning

Its oldest form is in the Duenos inscription,[2] and Köbler dates its first use in an inscription to the 4th century BC.[7] In literature de Vaan finds it first in Naevius;[2] the OLD's first example is Plautus' Trinummus, of a lover who becomes poor while he is kind to others.[5]

Semantic evolution

It describes people who are kind, obliging and affable, as Cicero's definition of the friendly, generous, easy and pleasant, and Horace's good neighbour kind to his wife;[5][4] it is also used of qualities and actions, such as Livy's friendly hospitality.[5] A second sense is having good taste, elegant or cultured, as Cicero's verse on Terence's refined speech and Horace's “youth is graceless without you” addressed to Venus.[5] Lewis & Short note that manuscripts often confuse it with commūnis.[4] Its noun is cōmitās, already in Plautus.[2]
