Definition
Meaning
A separate, often protective, piece of glass placed on top of another surface or display.

Linguistics
Semantic Notes
The term is a noun-noun compound where 'overlay' specifies the function (to lie over) and 'glass' specifies the material. In digital contexts, it can sometimes refer to a software graphical layer, but the physical object sense is primary.
Dialectal Variation
