Where does “leukopenia” come from?
I need to work through this etymology chain carefully, but I notice there's a significant problem with the chain as presented.
The chain appears to mix unrelated etymologies. "Leuko-" (from Ancient Greek λευκός meaning "white") has a clear PIE origin in *lewk- (to shine/be bright). However, the chain then lists πένομαι (pénomiai, "to lack/be in need") and traces it back through different PIE roots entirely. These are two separate etymological paths that wouldn't normally be chained together this way.
For "leukopenia" (a medical term meaning deficiency of white blood cells), the actual etymology should be:
- leuko- (white) + -penia (deficiency/poverty)
The chain as given doesn't properly support a coherent single etymology for the headword "leukopenia."
