Peculiarity → It is formed from "peculiaris" (meaning belonging to one person or private) and the suffix "-ity" (meaning the state or quality of). The word "peculiarity" refers to the state of being unique or distinctive to a particular individual or thing.
Think of something that is 'private' or 'belonging to one' — that's what makes it a peculiarity, a unique quality that sets it apart.
