Compositional

The compositional aspects of this work are less than ideal.

The phrase "sum of its parts" is entirely compositional.

A wet súit meaning a suit that is wet is a compositional phrase; a wét suit meaning a garment worn by skin divers is a compound.

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.
