هِيَ لَفْظٌ أُرِيدَ بِهِ لَازِمُ مَعْنَاهُ مَعَ جَوَازِ إِرَادَةِ ذَلِكَ الْمَعْنَى
Kinayah is an expression whose associated or implied meaning is intended, while the original meaning remains a permissible interpretation.
Lazim al-ma‘na is the meaning reached from the expression through a recognized association, custom, or typical consequence. It need not be an exceptionless logical implication: a long sword-strap or plentiful ash can function conventionally as a sign of a person’s quality.
