الصَّلَاةُ
Ritual prayer; lexically the term is also associated with supplication.
In legal discourse, “perform ṣalāh” normally invokes the established religious practice. A use of the same word meaning supplication belongs to a different lexical context, and its exact classification depends on the discourse.
The crucial difference is that a specialized conventional meaning need not be a fresh metaphor every time it occurs. A meaning can become established within a convention; a temporary figurative use works differently, through a relevant relation and contextual indication.
