Person and number agreement in American Sign Language

Abstract

American Sign Language (ASL) has a group of verbs showing agreement with the subject or/and object argument. There has not been analysis on especially number agreement. This paper analyzes person and number agreement within the HPSG framework. I discuss person and number hierarchy in ASL. The argument of agreement verbs can be omitted as in languages like Italian. The constraints on the type agreement-verb have the information on argument optionality.
