Question

Using APA, how do you cite a qoute from one source that has been qouted in the journal you are using for research?

Answer 1

Great question! You would never quote a quote. You would look into the paper's References to see which source the quote was from, and you would track down the original source and quote the primary, not the secondary, source.

Answer 2

You always want to read the full article that the quote was taken from, because the person who used the quote in the paper you are reading might have skewed its meaning by the way they used it in their paper. To fully understand what the original author was intending to say with the quote, you need to read the original journal article that the quote came from.
(so don't just toss the quote in your paper and steal the citation from the secondary article's References page)
