Etymology: "Brachials" is simply the plural of "brachial", so the word's history is that of the adjective. Its root is the Latin "bracchium", meaning "arm", which English borrowed through the adjective "bracchialis" (later spelled "brachialis") to describe things belonging to the arm. The word is a doublet of "brachialis", meaning the two forms descend from the same Latin source but reached English in slightly different shapes. In anatomy, the plural "brachials" usually refers to the arm-related structures grouped together, such as the brachial nerves or vessels. The Latin root also gave English the related "brachium", a term for the upper arm, which shows how closely the modern anatomical vocabulary still follows the classical original.
