Sometimes you need to use both double and single quotation marks in one sentence. Remember, this is the American manner of punctuating. The British system is the opposite of ours: they use single quotes where we use doubles.
Here is an American example: Joginder stated, “My classics professor assigned the first 40 pages of ‘The Odyssey’ for our next meeting.”
Normally, you would put “The Odyssey” in double quotes, but because it is within a statement that needs double quotes, you use single quotes for the “inside” one.
Joginder may ask, “Did Seema really say, ‘Why would I date him after the rude comment he made to me?’ “
That is a quoted question within another quoted question. Both sets of quotation marks come at the end of the sentence. It’s important to leave a space between the single and double quotes. Singles always come inside doubles (in America).
