finicky (adj.)youdaoicibaDictYouDict
1825, "dainty, mincing," from finical "too particular" (1590s), which perhaps is from fine (adj.) + -ical as in cynical, ironical (OED says "ultimate derivation" from the adjective "seems probable"). But finikin (1660s) "dainty, precise in trifles" has been proposed as a source, even though the timing is off. It apparently comes from Dutch; compare Middle Dutch fijnkens (adv.) "precisely, exactly," from fijn, cognate with English fine (adj.).
