المطابقة — التضمن — الالتزام
Complete signification, partial inclusion, and implication.
Signification is by matching when the whole assigned sense is conveyed, by inclusion when a constituent is conveyed, and by implication when the mind moves to an attendant sense. A merely accidental external association is insufficient.
First specify the assigned meaning of the expression, then decide whether the indicated content is the whole, a part, or an implication.
