Salikoko Mufwene raises significant questions about how and why languages become endangered (and die). The purpose of this reply is to provide additional perspective on what goes into answering these questions. Several of Mufwene’s claims are responded to. Questions are raised concerning what the theorizing about language endangerment and loss (LEL) that Mufwene calls for would be like. Many causal factors associated with LEL are mentioned, advances in understanding are pointed out, and the roles of language documentation and language revitalization are clarified.
