Forms

hilarē (comparative hilarius, superlative hilarissimē)[1]

Etymology

It is from Latin hilaris (“cheerful”) + -ē;[1] the OLD and Georges derive it from the variant hilarus.[2][3] The adjective was borrowed from Ancient Greek ἱλαρός (hilarós, “cheerful, merry”),[2][1] which Wiktionary derives from ἵλαος (hílaos, “propitious, gracious”).[1]

Earliest recorded meaning

Köbler and Georges find it first in Plautus,[4][3] who uses it of someone received cheerfully and generously.[3][5]

Semantic evolution

It means cheerfully, gaily or light-heartedly.[2][6] Afranius has a man showing himself cheerful, and the Rhetorica ad Herennium someone going cheerfully into the temple of Jupiter.[3][6] Cicero writes of living cheerfully, of treating stern matters cheerfully, and of Pompey being with him in good spirits while he wrote;[6][5] the comparative hilarius is used of speaking by Cicero and of writing by Pliny the Younger.[3][5] Gellius uses it of keeping the Saturnalia cheerfully but with restraint.[3][6] Columella applies it to plants, of their sprouting more vigorously.[3][5]

Augustine and the Vulgate use the form hilariter.[6]
