Three kinds of wording may occur in a critical discussion:
1. Technical noun: “This is a fard mutlaq” — an explicit formal classification.
2. Relational description: “Singular relative to teacher M” — the point of comparison is specified.
3. Derived verb: “N alone transmitted it” — singularity is asserted, but its full category may require the surrounding context.
In the second formula the specified relationship narrows the claim. The first explicitly names the overall class. The third may leave the precise location to be reconstructed from the isnad.
Distinguishing these functions develops an understanding of technical implication and scholarly usage, not merely a memorized list of words.
