overlay
This term describes the act of layering one thing atop another, whether physically or digitally. In a physical sense, it implies a protective or decorative addition that does not replace the original surface but sits on top of it. In digital contexts, it refers to a non-destructive layer of data or graphics that enhances a base image or stream without altering the underlying source file.
When used as a verb, the word often carries a technical or precise connotation, frequently appearing in fields like graphic design, cartography, and engineering. It is distinct from "cover," which suggests hiding the original surface entirely, whereas "overlay" suggests a relationship where both the base and the top layer are conceptually present or relevant.
Ý nghĩa
