This document discusses possession in American Sign Language (ASL). It explains that ASL uses personal pronouns and handshapes to indicate possession rather than "be" verbs. For example, signing a word with a flat "B" handshape and facing your palm toward the possessor. It also notes that possession can be shown through word order, such as signing "my mother dog" to indicate the dog belongs to the mother. The document provides examples of signs for different possessive pronouns like "mine", "his", and "theirs".
