ClassDiagnostic criterion
MuṭlaqahNo additional qualifiers of either side
MujarradahQualifying expressions suit the target
MurashshaḥahQualifying expressions suit the source image
These three qualifications must not be confused with the basic distinction between non-similarity transfer and metaphor. One first establishes resemblance as the relation, then considers which side the auxiliary expressions fit.
Every class still requires a contextual indicator of nonliteral intention; that is distinct from tarshīḥ and tajrīd.
