One objection arises when “ṭawīl al-nijād” is applied to someone who has no sword strap. How can a literal reading remain possible? The definition describes a kind of linguistic use, not an assertion that the physical object exists for every referent.
A construction capable of referring to an actually long strap can also allude to height even when the speaker intends only the associated attribute. “The concomitant is intended” and “the literal claim is actually true here” are separate propositions.
Conversely, if added context deliberately excludes the original meaning, the resulting usage requires a fresh classification.
