Learn English – A phrase whose meaning is different from a combination of its constituents

expressionsphrase-requestsphrases

The are phrases whose meaning is not what you would get from combining its constituent words (i.e., they violate the Principle of compositionality).

  1. Some are entity names, e.g.,
    • "weird science" is (usually) a movie, not a kind of science,
    • "grand theft auto" is a specific kind of felony or a computer game, not stealing a big car
  2. Others are idioms, e.g.,
    • "kick a bucket" or
    • "pull a leg" or
    • "break a leg"
  3. something else which escapes my mind at the moment…

What is the general term for this?

"Non-compositional phrase"?

The only other thing which comes to mind is mass-defective phrase 🙂

What you describe is referred to as a multiword expression (MWE) - one definition of which is idiosyncratic interpretations that cross word boundaries (or spaces). A fuller description (too detailed to be sensibly reproduced) can be found here.

Examples include: kick the bucket, throw to the lions.
