Q: Question: A simple question that has sparked some debate, and I couldn't find a concrete answer anywhere. There seems to be two camps: The word plethora indicates plural, so therefore it should be "There are a plethora"; and the other camp says that there is only one plethora (which contains multiple), so it should be "There is a plethora". I've seen many examples of both. Is there a consensus, or is it just one of those things that can go either way?
Answer: A plethora is singular, so one must say "there is a plethora of..." just as one would say "there is a bunch..." If you are dealing in several plethoras, you could use the plural: "there are plethoras of..." but this feels very contrived and artificial.
A:
yes
