fidge
To fidget; jostle or shake.
obsolete
"Look, Jim, how my fingers fidges," he continued in the pleading tone. "I can't keep 'em still, not I. I haven't had a drop this blessed day. That doctor's a fool, I tell you. If I don't have a dram o' rum, Jim, I'll have the horrors..."
Where it comes from
Probably an assibilated form of Middle English fiken (“to jitter; move restlessly; hustle; flinch; hasten away”), perhaps related to Old English befician (“to deceive”) or from Old Norse fika (“to climb up nimbly, as a spider”), akin to Norwegian fika (“to strive after”), Swedish fika (“to strive for; hurry”). See also fike.
