The word "branch off" can be analyzed by examining the etymology of its two components: "branch" and "off".
1. "Branch":
The term "branch" originated in Middle English, derived from the Old French word "branche", which means "twig". The word can be traced further back to the Late Latin term "branca", which translates to "limb" or "branch". The ultimate root is uncertain, but it is believed to have Germanic origins.
2. "Off":
The word "off" comes from Old English, where it was written as "of". Its origin can be attributed to the Proto-Germanic word "*af", which carries a similar meaning of "away" or "from". This Proto-Germanic root also contributed to other Germanic languages like German ("ab") and Dutch ("af").
