Etymology: "Antecubital" is a plain technical formation: the prefix "ante-", meaning "before" or "in front of", joined to "cubital", the adjective from Latin "cubitum", "elbow". Together they describe the front of the elbow, the soft hollow on the inner arm where the skin is thin and veins lie close to the surface. "Cubitum" also gave English "cubit", the ancient measure of the length from elbow to fingertip, which is a useful way to remember the root. The "-al" ending turns the noun into an adjective, so "antecubital" modifies things such as a vein, fossa, or space. Its use is confined to anatomy and medicine, where it was built from classical elements to name a precise body region.
