Mushtarak: an expression assigned to two or more genuinely distinct meanings. The source illustrates it with jariyah, mushtari, and qurʾ. Once one sense is intended in an occurrence, the alternative is not also intended there.
Muʾawwal: one sense is preferred by reasoned preponderance; it is acted upon although error remains possible. The Hanafi preference for menstruation as qurʾ is the source example.
Mufassar: the footnote describes meaning clarified by the speaker, with categorical application in that case.
The next division is based on usage: ḥaqīqah, majāz, ṣarīḥ, and kināyah.
