I feel like we don't need to have both premodifiers and quantifiers tags, because I don't understand what the difference is supposed to be, and I doubt everyone else does either. Neither has a tag wiki to explain exactly what questions are supposed to be included.
It would be best in my opinion to have a single tag for all of the questions about "X of Y" constructions like "a number of cats", "the number of dogs", "50% of people", etc.
Dictionaries seem to define "premodifier" in an incredibly vague way that includes things like attributive adjectives. However, partway through attempting to retag all the premodifiers questions (since they seem to be fewer than quantifers questions), I decided to stop and pose the question to Meta. It seems vaguely plausible to me that "quantifiers" actually has some inconveniently technical definition that excludes some of these constructions, and so someone would object to using it on all of these questions.
What are people's thoughts about the best way to categorize questions on this subject? It would be nice if the criteria don't require the asker to know the agreement pattern of the construction in question, since lots of the questions are about this very issue.
