Pronunciation


The etymology is consistent with the /u/ in the first syllable being short, and the word is shown without a macron in De Vaan's dictionary. Although Bennett 1907 says "ū acc. to the Romance", there are related words in Romance that point to short u in the descendants of the derivative *, such as Old French froissier.

Noun

 * 1) a piece, bit; crumb, morsel, scrap of food
