ASL Phonology refers to the study of the basic units of meaning in American Sign Language. It examines how signs are formed and structured, focusing on parameters such as handshape, location, movement, palm orientation, and facial expressions. These elements combine to create distinct signs that convey specific meanings. In ASL, each sign can be broken down into these phonological components, similar to how spoken languages use sounds. Understanding ASL Phonology helps learners recognize patterns in signs and improves their ability to communicate effectively in the language.
