I think GG said in a post that American style guides put commas and periods inside the quotation marks, always. OK. Does that mean they are to be followed regardless how short or long the ones in quotation are?
eg,
... such as 'a,' 'an,' or 'the.'
How about if I use double apostrophes, is the American style guide permit that?
... such as "a," "an," or "the."
Please note (I presume you already have noticed it) these are very short words.
