لَفْظٌ أُرِيدَ بِهِ لَازِمُ مَعْنَاهُ مَعَ جَوَازِ إِرَادَةِ ذَلِكَ الْمَعْنَى مَعَ لَازِمِهِ
An expression used to intend a concomitant of its meaning, while also allowing its own meaning to be intended.
The definition contains two essential conditions. First, the intended meaning is a consequence or concomitant of the expression's apparent sense. Second, the literal sense is not excluded in principle. An indirect formulation is therefore insufficient unless a recognizable connection leads to the intended meaning.
The definition says that literal intention is permissible, not that it actually occurs in every instance. The possibility of literal intention, rather than its necessary actuality, is the defining point.
