Forms
laetitia f (genitive laetitiae); first declension[1]
Etymology
It is formed from Latin laetus (“glad, joyful”) + -itia.[1][2][3][4] The origin of laetus is unknown: Walde, Hofmann and Pokorny took “fat, rich” as its first sense and linked it with lārdum (“bacon”) and largus (“generous”), a reconstruction de Vaan calls very artificial.[5][4] Isidore explained the spelling with a diphthong by deriving the word from lātitūdō (“breadth”).[3]
Earliest recorded meaning
De Vaan and Köbler date it from Plautus,[5][6] who has iste pariet laetitiam labōs, “that labour will bring forth joy”.[2]
Semantic evolution
Laetitia is joy, gladness, delight, especially joy that shows itself openly, Cicero defines it as the fresh belief in a present good that makes one feel elated.[2][7] Like laetus, it is also used of land and plants, “fertility, luxuriance” (Columella), and in Tacitus of a florid, ornate style.[2]
Döderlein contrasts gaudēre, joy as an inner state, with laetārī, joy expressed outwardly.[8] Church Latin glosses it “gladness, happiness, delight”.[9] The English name Letitia comes from it.[4]
