If syntactically covert variables rather than multiple lexical entries account for interpretive flexibility, then the scope of genuine ambiguity does not expand but remains narrow.

Ambiguity(as used in linguistics and philosophy of language): When something can be understood or interpreted in more than one way.
Interpretive flexibility(describing how the word 'yawm' can be understood in different ways): The quality of a text or concept that can be understood in multiple different ways, depending on how you read it or what assumptions you bring to it.
Lexical entries(how many word meanings exist in language): Individual words or word meanings listed in a dictionary or language system—essentially, the official catalog of words a language contains.
Scope of genuine ambiguity(philosophy of language): The range or extent of situations where something truly has more than one possible meaning (as opposed to just appearing to have multiple meanings).
