grucwrinkle
verbStrong class 2to fold, wrinkleto stoop, crawlAccording to Kroonen, the verb was associated by the Germanic tribes with the unrelated *kreupaną (‘to crawl’) from an early stage. He suggests that the root final -k arose from an earlier geminate -kk, which was adopted from the iterative verb *krukkōną. Related to Old Irish gruc (‘wrinkle’).
