Morphology
arcus + senilis
The phrase is a straightforward Latin compound: 'arcus' refers to an arc/whitish deposit at the corneal edge and 'senilis' means 'of old age' (cognate with English 'senile' and similar forms in many languages). A learner who knows both constituents can directly infer it denotes an age-related arc on the cornea, so the meaning is compositional and transparent.
Etymology
Arcus senilis comes from the Latin words arcus ('arch') and senilis ('old'), and it describes a pale, curved ring at the edge of the eye. That's why the name helps you remember this harmless gray or white arc often seen in older people, which usually does not affect vision.
