fimble

From Middle Dutch femele, fimele (“cannabis brevior”), from fimelen (“to tease: flax, hemp, wool, etc.; to move quickly, fiddle, play, trifle”) (whence Dutch fijmelen, femelen), related to Middle Low German fimmelen, fimmeren (“to grope about”), German fimmeln (“to grope; fumble”), West Frisian fimelje (“to pick; fiddle' trifle”), English fimble (“to fumble”). Alternatively, it is sometimes suggested that Middle Dutch femele is from French chanvre) femelle (“female (hemp)”), which was applied to the male hemp plant as it is smaller and was therefore believed to be female; this would parallel the old designation of the larger, female plant as carl-hemp (“man-hemp”).
