"Pernickety" describes someone excessively concerned with minor details and trivial matters. It's similar to being fussy, but often implies being annoying or overly critical. Imagine a person who corrects everyone's grammar constantly! Pernickety people can be difficult to please because they focus on small imperfections. Think of someone who complains about the placement of cutlery at a restaurant. It's the opposite of being laid-back and easygoing. Being pernickety can strain relationships.
