Morphology

efferent = ef + fer + ent

Formed from Latin combining elements (ef- + fer + -ent) that are not recognizable as standalone English words to an average B1 learner, and the term is technical.

Etymology

Efferent comes from the Latin parts ex- meaning 'out' and ferre meaning 'to carry'. That's why, as an adjective, efferent describes nerves or signals that carry information away from the brain or spinal cord.
