connector; association element
Technical term used in logic, linguistics, and formal systems to refer to a symbol or element that joins components. Not a general-purpose word for 'connection'.
In logic, a connector is a symbol that links propositions.
In this formal language, we use '∧' and '∨' as connectors.
Compound of 結合 (ketsugō, 'combination, union') and 子 (shi, 'element, child'). The derivation is straightforward; 子 is a common suffix for technical terms.
