ASL Morphology refers to the structure and formation of signs in American Sign Language. It involves the use of handshapes, movements, and facial expressions to convey meaning. Just like spoken languages have prefixes and suffixes, ASL has its own ways of modifying signs to create new meanings or grammatical forms. In ASL, signs can be combined or altered to express different concepts, such as tense or plurality. For example, the sign for "run" can change in movement to indicate "running" versus "ran." Understanding ASL morphology helps learners grasp the complexity and richness of the language.
