Morphology

otolith + organ

Given knowledge of 'otolith' (a hard inner-ear structure involved in balance) and 'organ' (an internal body part with a function), a learner can straightforwardly infer that an 'otolith organ' is an organ composed of or containing otoliths that serves a balance-related function. The noun–noun composition is transparent and follows normal English compounding patterns, so the overall meaning is directly derivable from the constituents.

Etymology

The noun otolith organ comes from words meaning ear and stone, a helpful image: tiny stones sit on a soft layer in the inner ear and move when you tilt your head. When the stones press on tiny hairs they tell the brain about 'gravity' and 'straight-line movement', so the organ helps you keep your balance.
