*grewbʰ-to crawlgrubinė́tito stumble
verbStrong class 2to writhe, twist, windto creep, crawlAccording to Kroonen, the derivations containing -p(p)- and -b(b)- show that the root was originally Pre-Germanic *kreupp-, from Proto-Indo-European *grewbʰ- (‘to crawl’), rather than the traditionally given *grewb-. He gives Lithuanian grubinė́ti (‘to stumble’) as a cognate.
