I shall tactfully refrain from naming the author or title of the book (published by a highly reputed university press) in which I found the following sentence:
“One might argue that romances, like novellas, were the kind of prose fiction that was closest in interest and narrative type to romances.”
One might argue that; but why would one bother? It’s tautological.
Maybe one or more adjectives is missing, or something else went wrong in the editing process. In the context of the paragraph, it seems like a different kind of statement is needed at this point. I can imagine highlighting and moving the wrong chunk of text.
Note to self as well as others: this is why actual proof-reading by human eyes (and, preferably, voice) is necessary. Do not rely on electronic checkers of spelling and grammar.
