Can a singular noun represent a plural non-collective noun?
I was reading an old novel, British English written around 1850. I came across the phrase “I saw signs of elephant in the forest”. This intrigued me as the word "elephant" implies anything from a single to multiple animals. The word "signs" seems to have taken on the role of plurality for the noun. I was asked a similar question by my partner who is editing a book in which the phrase “I saw fairy dancing in the woods,” not meaning a single fairy but many fairies dancing. Can anyone expand my knowledge on the use of a singular noun being used as a non-collective plural noun?
