Reconstruction:Proto-Germanic/lustuz

This Proto-Germanic entry contains reconstructed terms and roots. As such, the term(s) in this entry are not directly attested, but are hypothesized to have existed based on comparative evidence.

A tu-stem nominal formation from a root *lus-, whose further origin is disputed:^[1]

• Traditionally derived from Proto-Indo-European *leh₂s- (“to be eager”), and compared with Ancient Greek λῐλαίομαι (lilaíomai, “to desire, long for”), Latin lascīvus (“wanton, lustful, lascivious”), Old Irish lainn (“avaricious”), Proto-Slavic *lasъ (“greedy, eager”), Lithuanian lokšnùs (“sensitive”). However, this assumes an awkward secondary zero-grade form of *lh₂s- for the Germanic and all potential cognates except the Balto-Slavic.
• Possibly derived from *leusaną (“to lose, empty”) +‎ *-þuz, with semantic shift "lost, empty" > "idle" > "frivolous" > "lustful". In this case, ultimately from Proto-Indo-European *lewH- (“to separate, loosen, release”). This derivation is tentatively favored by Kroonen.
