Morphology

cat's + eye

The phrase evokes a resemblance to a cat's eye (shiny/reflective), so a learner who knows 'cat' and 'eye' can plausibly infer it names something that looks or shines like an eye. However, the specific conventional referents (a road reflector or a particular type of marble) are lexicalized senses that are not fully predictable from the parts alone, making the expression only partially transparent.

Etymology

Cat's eye comes from a thin, bright band of light that seems to move across a polished stone, like a real cat's pupil when it catches light. So, the name now means a gem that shows this eye-like shine.
