Extremely particular, fussy, or hard to please about details; requiring careful attention to small things.
Likely derived from 'finick' (of uncertain origin, possibly from Dutch 'finisch' or related to fine), with -al suffix added. The word emerged in the 1600s to describe someone overly concerned with minor details.
The word 'finical' captures a very real personality type—some people's brains are literally wired to notice tiny inconsistencies that others completely miss, and while it can be annoying, it's also why we have proofreaders, quality inspectors, and watchmakers!
