One way to hold this word: a pair of hands busy on a fiddle — fingers moving in small, quick, constant adjustments, and one arm held up against the body. Every fiddler in English comes from part of that picture. From the sound, the musician. From the restless fingers, the person who keeps adjusting, and then the person who quietly adjusts numbers. From the raised arm, a crab on the mud that looks as if it is holding a violin.
From the word’s history
The packet's Wiktionary etymology gives fiddler as fiddle + -er, through Middle English fithelere and Old English fiþelere, so the word starts as 'the one working the fiddle'. It also records that the crab is named from the way the male holds his enlarged claw, like a musician holding a fiddle.
封包裡的字源說，fiddler 是 fiddle 加上 -er，經中古英語 fithelere、古英語 fiþelere 而來，字面就是「弄那把琴的人」。同一份資料也記下螃蟹得名的理由：公蟹舉著大螯的樣子，像音樂家夾著琴。所以這個字後來的分支，都還能回到那雙手上。
