In many descriptions of American Sign Language (ASL), signs like [breakfast] are identified as "compounds." These signs were once formed with two separate signs but have since fused into a single unit. This article presents an alternative definition of "compound" that includes both functional and formal properties. Following this updated definition, examples of ASL compounds are constructions like [name sign] and [sign language], which combine two object-concept words to name an object concept, as well as related constructions like [formal room] 'living room,' which also label object concepts. The updated definition of "compound" allows for terminological consistency and sets the stage for fuller understanding of the variety of multisign units in ASL.
