When 'curious' is used as an adjective (e.g., in the construction "A is a curious B"), there is ambiguity as to whether the noun it modifies is:-
- The subject: A feels curious (e.g., "Humans are a curious species" meaning humans want to know about everything)
- An object: A is an object of curiosity (e.g., "Dung beetles are a curious species" meaning dung beetles are interesting to us)
How can we resolve this ambiguity? Is there an official way to do it? Both are correct 'de facto' as both versions of usage are common.
