The word "fiat" comes directly from Latin, where it means "let it be done." It is the third-person singular present subjunctive form of the verb "fieri" (to become or be done). Historically, it was used in formal decrees, such as the phrase "fiat lux" ("let there be light") in the Latin Bible. Over time, it evolved into English to signify an authoritative command or arbitrary decision, often by a government or ruler. The word retains its original spelling and meaning, reflecting its legal and formal roots.
