I am struggling with an exercise. I have not studied English grammar for years so do not remember much. My questions concerns headwords in the following sentences:
- the dog with the collar
- may work
- may have worked
My first thought was that "dog" is the headword in (1), making "with the collar" a postmodifier? The other two examples are trickier. When I asked myself: "what does "may" refer to", the answer of course is "work". Which leads me to think that "work" is the headword in both (2) and (3). Or is there a difference between (2) and (3)? That is my guess since both sentences were included...
Any help would be appreciated!
