Does anyone know or can suggest a term for the following expressions:
lady-in-waiting brother-in-law sergent-at-arms bride-to-be etc.
Expressions like those above are special for (at least) two reasons:
1. The plural attaches to the first noun, rather than to the entire expression, hence
2. The dependent PPs do not seem to be modifiable, hence the next examples are bad:
There is more that distinguishes these expressions from nouns with adjunct PPs, but this should suffice as background.
Any ideas what these expressions are called? Or do you have a suggestion?
