I am reading a paper "Aspectual Categories in Navajo" and the author refers to something called a "verb constellation:"
Verb constellations are associated with the situation types of a language. Since certain temporal semantic features are intrinsic to a given situation concept, they are expressed by the verb constellation. In the discussion, I use brackets for verb constellations [...]
The term is not defined in the paper, and I was unable to find a definition by Googling. Based on the context, I think the term may be specific to generative grammar.
For additional reference, the author refers to "[Mary walk by the river]" as an example of a verb constellation. To me, this just looks like a sentence with the verbal morphology removed, but I assume something more interesting is being done.
