The quality of being very particular about details, often to the point of being fussy or hard to please.

Persnicketiness is derived from the word 'persnickety' which is believed to come from the Scottish dialect 'persnickety' (meaning fussy or finicky). The suffix '-ness' (meaning the state or quality of) is added to form a noun. Therefore, 'persnicketiness' refers to the quality of being fussy or overly particular.
Think of someone who is very 'fussy' or 'finicky' — that's what 'persnicketiness' means, the state of being overly particular.
