Morphology

afferent = af + fer + ent

Although analyzable as af- (assimilation of ad-) + fer + -ent, these Latin combining forms are not productive English morphemes and a typical learner cannot derive the meaning from familiar English words.

Etymology

Afferent comes from Latin ad- 'to' and ferre 'to carry'. So when a pathway is afferent, it is 'carrying to' the brain and spinal cord — in other words, it brings sensory signals toward the body's control center.
