In blending theory, one of the three component processes that give rise to emergent structure.

For instance, in the Clinton as French president integration network, due to the utterance: In France, Clinton wouldn't have been harmed by his affair with Monica Lewinsky, composition brings together the value bill Clinton with the role French president in the blended space, resulting in the emergent structure: Clinton as French president. See the entry for conceptual integration where this blend is described in detail.
