In language-oriented programming and modeling, software developers are largely concerned with the definition of domainspecific languages (DSLs) and their composition. While various implementation techniques and frameworks exist for defining DSLs, language composition has not obtained enough attention and is not well-enough understood. In particular, there is a lack of precise terminology for describing observations about language composition in theory and in existing language-development
more » ... . To clarify the issue, we specify five forms of language composition: language extension, language restriction, language unification, self-extension, and extension composition. We illustrate this classification by various examples and apply it to discuss the performance of different language-development systems with respect to language composition. We hope that the terminology provided by our classification will enable more precise communication on language composition.
