Morphology

rotational + nystagmus

The adjective 'rotational' straightforwardly modifies the noun 'nystagmus', so the meaning is simply 'a nystagmus that occurs during or is caused by rotation'. This adjective+noun composition is compositional and cross-linguistically common, so a learner who knows both constituents can derive the overall meaning.

Etymology

Rotational nystagmus comes from the simple image of the eyes moving when the body turns. Rotational means 'turning' and nystagmus names the eyes' back-and-forth movement, so when you spin your eyes move this way without meaning to and the world can seem to keep turning.
