What is off? How to use in English

The word "off" has a rich history! The Old English word "off" was derived from the Proto-Germanic word "*afuzz", which meant "away" or "from". This Proto-Germanic word is also thought to be related to the Latin word "ab", also meaning "away" or "from". In Old English, "off" was used to indicate separation or removal, as in "off" fen (from the fen) or "off" ship (from the ship). The word also developed negative connotations, such as "off-kilter" (crooked) or "off-color" (ill). Throughout Middle English and Early Modern English, "off" continued to evolve, taking on new meanings and shades of meaning. By the 18th century, "off" had become a versatile preposition, able to indicate separation, removal, or rejection (e.g., "off the hook", "off to bed"). Today, "off" is a fundamental part of English language, with numerous uses and meanings.
