Pronunciation

Forms

iūcundus (feminine iūcunda, neuter iūcundum, comparative iūcundior, superlative iūcundissimus, adverb iūcundē); first/second-declension adjective[1] It is also spelled iōcundus, influenced by iocus “joke”.[2][3]

Etymology

It is from iuvō “to help, delight” with the suffix -cundus, through ⟨*iuwicondos⟩.[2][1][4]

Earliest recorded meaning

The OLD's earliest citation is from Plautus, of pleasant experiences.[2] Köbler dates Plautus c. 250–184 BC.[4]

Semantic evolution

It meant pleasant, agreeable, delightful, as in Plautus, in Cicero of people congenial, and in Lucilius agreeable to the senses.[2] Döderlein explains that grātum is what is welcome only for its value to us.[5]

In Ecclesiastical Latin it meant pleasing, acceptable, happy.[6] British Medieval Latin used it of things pleasing to the senses and of agreeable experiences.[7] It survives in Italian giocondo and Spanish jocundo, and through Old French it gave English jocund in the late 14th century.[1][3]
