Morphology

autonomic + nervous + system

The phrase is fully compositional: 'autonomic' (involuntary regulation) + 'nervous' (relating to nerves) + 'system' (a set of cooperating parts) directly yields 'the part of the nervous system controlling involuntary functions.' This modifier–noun stacking is a standard productive pattern in English (and has clear equivalents in many languages), so a learner who knows the constituents can reasonably infer the meaning.

Etymology

Autonomic nervous system gets its name from the idea that autonomic means 'working by itself' — think of a clock that keeps going without someone touching it. So, it describes the body system that controls the heartbeat, breathing and digestion 'without thinking'.
