Having recently learned about frequentative forms, I began to wonder, is fiddle a frequentative form? I've seen the suggestion that
-le in this case was a pre-English formation, but the meaning "to touch or handle something in a nervous way," as well as some of the others (such as playing a violin) have a distinctly frequentative idea which makes me question that claim. Also, it makes me wonder: how far back in the history of English does
-le to form frequentatives go?
Is there compelling evidence to decide the question of whether fiddle should be considered a frequentative form? If it is, what is the root form? (Or perhaps that assumes too much and I should also ask: Does a frequentative form always have a root, or would some actions only exist in a frequentative form?)
