Forms

aphorismus m (genitive aphorismī); second declension[1] Medieval scribes also wrote aforismus, afforismus, amphorismus and anforismus.[2][3]

Etymology

It is borrowed from Ancient Greek ἀφορισμός (aphorismós, “definition; short pithy sentence”),[4][5][6] a noun from ἀφορίζω (aphorízō, “to mark off, divide”), from ἀπό (apó, “from”) and ὁρίζω (horízō, “to bound”).[6][3] Niermeyer ties its use to the title of the work of Hippocrates.[7]

Earliest recorded meaning

Jerome (writing c. 383–420 AD) is the earliest writer in Conte's citations: “Hippocrates teaches in his Aphorisms”.[8][4][3] The TLL notes that the word seems to occur only in the plural, for that Hippocratic book.[4]

Semantic evolution

Caelius Aurelianus refers to his explanatory book on the aphorisms of Hippocrates,[4][5] and Isidore of Seville, among the medical books, defines an aphorism as a brief saying that sets out the whole sense of a matter.[4][5]

In Medieval Latin it was used more widely for a definition or pithy saying,[2][9] and especially in the titles of medical books, those of Hippocrates and of other physicians.[2][9] Through French it gave English aphorism in the 1520s.[6]
