declarator
A computing term for a syntactic element that declares a variable, function, or type in programming languages. Rare outside technical contexts.
In C, declarators specify a variable’s name and type.
Compound of 宣言 (declaration) and 子 (a suffix used in computing for syntactic elements, akin to 'operator' or 'specifier'). The exact origin is uncertain; likely a calque from English 'declarator'.
