Persnickety originates from the Scottish dialect, where 'persnickety' is derived from 'persnick' (meaning to be finicky or fussy) and the diminutive suffix '-ety'. The word describes someone who is overly particular or hard to please, often in trivial matters.
Think of someone being 'fussy' or 'finicky' about small details — that's what persnickety means.
