Without further ado, here is the next set of words:
Addition vs. Edition
Wrong: The fifth addition of his book just came out.
Right: The fifth edition of his book just came out.
Given how common both words are, I’m surprised at how often I see addition confused with edition. An addition is something that is added, while an edition is a form in which text is printed. A special holiday section of a newspaper might be said to be an addition to the edition.
Melt(ed/ing) vs. meld(ed/ing)
Wrong: I’m looking forward to the melting of our cultures.
Right: I’m looking forward to the melding of our cultures.
