Etymology

From Middle English crabbe, from Old English crabba (“crab; crayfish; cancer”), from Proto-West Germanic *krabbō, from Proto-Germanic *krabbô, from *krabbōną (“to creep, crawl”), from Proto-Indo-European *grobʰeh₂yéti (“scratch, claw at”), a metathesised o-grade of *gerbʰ- (“to carve, scratch”). More at carve. Cognates See also Dutch krab, Low German Krabb, Danish krabbe, Swedish krabba. Further cognates with frequentative-infix are Saterland Frisian krabbelje (“to creep, crawl”), Dutch krabbelen (“to scratch”) and German krabbeln (“to crawl”). Possibly related to English creep and Swedish krypa (“to creep, crawl”) etc. Other origins have also been suggested, see Ancient Greek κάραβος (kárabos) (regarding the possibility of a substrate origin) and Persian خرچنگ (regarding possible ideophonic origin); compare also Old Armenian քարբ (kʻarb), German Krebs.
