Reserved words are words that a
programming language has set aside for its own use.
In a computer language, a reserved word
(also known as a reserved identifier) is a word that cannot be used as an
identifier, such as the name of a variable, function, or label – it is
"reserved from use". This is a syntactic definition, and a reserved
word may have no meaning.
A closely related and often conflated
notion is a keyword, which is a word with special meaning in a particular
context. This is a semantic definition. By contrast, names in a standard
library but not built into the language are not considered reserved words or
keywords. The terms "reserved word" and "keyword" are often
used interchangeably – one may say that a reserved word is "reserved for
use as a keyword" – and formal use varies from language to language; for
this article we distinguish as above.
