Etymology tree
Forms
lūctuōsus (feminine lūctuōsa, neuter lūctuōsum, comparative lūctuōsior, superlative lūctuōsissimus); first/second-declension adjective[1]
Etymology
It is from Latin lūctus (“grief, mourning”) + -ōsus.[2][3][1] The noun is from lūgeō (“to mourn”), which goes back to Proto-Italic *loug-eje-; de Vaan reconstructs Proto-Indo-European *loug-eie- (“to swallow, gasp”), though the root is disputed.[4] On that view it is cognate with Ancient Greek λύζω (lúzō, “to hiccup, sob”).[4]
Earliest recorded meaning
Köbler's first source is Cicero,[5] who writes that it is grievous to be handed over to another with one's goods, more grievous to an enemy.[2]
Semantic evolution
It means causing sorrow, grievous or calamitous, as in Cicero's “O that day, so grievous for the state”.[2][6] It also means sorrowful or mournful, as in Cicero's “the wretched and mournful prayers of my brother”, and in Horace.[2]
Church Latin glosses it “sorrowful, sad, mournful”.[7] In medieval law hereditas luctuosa is an inheritance that passes to the parents on the death of their child.[8]
