frolic

From Dutch vrolijk (“cheerful”), from Middle Dutch vrolijc, from Old Dutch frōlīk, from Proto-Germanic *frawalīkaz. Compare German fröhlich (“blitheful, gaily, happy, merry”). The first element, ultimately from Proto-Germanic frawaz, is cognate with Middle English frow (“hasty”); the latter element, ultimately from -līkaz, is cognate with -ly, -like.
