The word can be read in three pieces: im- (into), person, -ate (do). One way to hold it is 'step into a person'. You put on someone's face, voice and walk and move around inside them for a while. Everything the word does turns on one question: does anyone believe it is really them? When yes, it is a con. When no, it is a performance. In computing, the 'person' you step into is an account.
From the word’s history
Wiktionary's tree gives im- + person + -ate, with person going back through Middle English persoun to Latin persōna. The modern verb still says exactly that: to put a person on.
字源資料把它拆成 im- ＋ person ＋ -ate，person 經中古英語 persoun 回到拉丁文 persōna。今天的動詞講的還是同一件事：把一個人穿上身。
