 Bound and unbound readings of pronouns give rise to similar problems, though whether this is a semantic, syntactic or pragmatic ambiguity has been the source of heated debate. If I tell you ‘everyone loves his mother’, the sentence may be interpreted with ‘his’ being co-indexed with ‘everyone’ and yielding different mothers (potentially) for different values of ‘everyone’ or it could be interpreted deictically saying that everyone loves that [appropriate demonstration] guy’s mother. Static semantics usually treats the distinction between bound and free pronouns as a fundamental ambiguity; dynamic semantics relegates the distinction to an ambiguity in variable choice (see Heim 1982, 1983, and Kamp 1981).
