Non-denial denial
A non-denial denial is a statement that, at first hearing, seems to be a direct denial of some allegation or accusation, but after being parsed carefully turns out not to be a denial at all, and is thus not explicitly untruthful if the allegation is in fact correct. It is a case in which words that are literally true are used to convey a false impression; analysis of whether or when such behavior constitutes lying is a long-standing issue in ethics.
