### Etymology

From Proto-Indo-European *leb- (“to hang loosely”), making it cognate with Proto-Germanic *lepô (“lip”), although (as with many other roots reconstructed with *b) there is some doubt about whether this root goes back to Proto-Indo-European. Lab- may be the regular outcome of zero-grade tautosyllabic *l̥b.-. Doublet of labrum.
