Wurdahuzdą: Proto-Germanic dictionary

noun masculine a-stem a body; mass a compressed, round mass; lump; ball a group; bunch; collection a crop; bunch; cluster; head (of grain) a crop Traditionally derived from a Proto-Indo-European *grewb- (‘to curve, bend, crawl’), from a root Proto-Indo-European *ger- (‘to turn, wind (into a mass)’), and compared with Persian گروه (goruh, ‘group’), though the reconstruction appears outdated (as more recent research reconstructs the proto-root as *grewbʰ-, see the entry for *kreupaną linked below), and the existence of a more fundamental root *ger- appears quite uncertain. Kroonen tentatively considers the word an a-stem nominal formation related to *kruppōną (‘to crawl’), itself the iterative to *kreupaną (‘to crawl, writhe’), via sense development "to bend down and crawl" > "to bunch oneself into a clump-like shape".
