Forms
hilaris (neuter hilare, comparative hilarior, superlative hilarissimus, adverb hilarē or hilariter); third-declension two-termination adjective[1] Also hilarus, -a, -um, the form under which the OLD enters it.[2]
Etymology
It is borrowed from Ancient Greek ἱλαρός (hilarós, “cheerful, merry”), from ἵλαος (hílaos, “propitious, gracious”).[2][1][3] Etymonline relates the Greek to a root *selh- “to reconcile”, as in sōlor “to comfort”.[4]
Earliest recorded meaning
The OLD's earliest citations are from Plautus, of a cheerful slave, in the form hilarus.[2] Köbler dates Plautus c. 250–184 BC.[5]
Semantic evolution
It meant cheerful, light-hearted, of good cheer, as Plautus' hilarissumum convīvam and Cicero's hilarī animō esse, and of features and expression cheerful, and in Columella of animals lively.[2][6] Of events and writings it meant marked by cheerfulness, as Cicero's hilara Sāturnālia, and of things cheerful in aspect.[2] Döderlein explains that gaudēre is joy as an inward state, while laetārī and hilarem esse are its outward expression.[7]
In Ecclesiastical Latin it meant cheerful, joyful, smiling.[8] British Medieval Latin used it of happiness and of a cheerful face or voice.[9] English hilarious came in 1823 from it, first “cheerful”.[4]
