A named programming language, the one most of the web runs on. A named tool rather than a concept.
Coined in 1995 as a marketing name riding Java's popularity, though the language itself descends more from Scheme and Self than from Java; script, from Latin scribere (to write), names a small program run by another program rather than compiled alone.
A named tool whose name was chosen for what it could borrow from another language's popularity, not for what it actually descended from.
