   “We have already noted that compounds tend to have meanings that are not entirely compositional and would therefore need to be listed.”

   “Sentence meaning is compositional because, to a large extent, it depends on a combination of the meanings of sentence constituents, which implies the concept of semantic structure.”

   “To cite a textbook example, white house and White House are both written with internal spaces, but the first is argued to be a phrase because it is semantically compositional and has phrase-final stress, while the latter is argued to be a word because it has noncompositional semantics and compound-initial stress.”
