The borrowed expression, or the speaker's act of employing that expression figuratively.
The term istiʿārah can denote the word used as a metaphor or the act of borrowing its use. The verbal noun sense accounts for the related terminology.
When “asad” is said of a brave human:
Mustaʿār minhu — the original lion meaning, from which the word is borrowed.
Mustaʿār lahu — the courageous human, for whom it is employed.
Mustaʿār — the borrowed expression “asad.”
Keeping the word, original concept and intended referent distinct prevents confusion in later classifications of metaphor.
