وكلٌّ منهما لغويٌّ وشرعيٌّ وعُرفيٌّ خاصٌّ أو عُرفيٌّ عامٌّ
Both literal and figurative usage can be lexical, religious, specialized customary, or generally customary.
Lexical refers to linguistic usage; religious to a religiously established convention; specialized customary to a technical community; and general customary to broad accepted usage without a particular identifiable institution responsible for the transfer.
The technical sense of “fiʿl” among grammarians illustrates a specialized convention, while the restricted use of “dābbah” for a four-footed creature illustrates general conventional usage.
