Enthymeme (en’-thy-meem): 1. The informal method [or figure] of reasoning typical of rhetorical discourse. The enthymeme is sometimes defined as a “truncated syllogism” since either the major or minor premise found in that more formal method of reasoning is left implied. The enthymeme typically occurs as a conclusion coupled with a reason. When several enthymemes are linked together, this becomes sorites. 2. A figure of speech which bases a conclusion on the truth of its contrary. [Depending on its grammatical structure and specific word choice, it may be chiasmus].
1. We made it to New Hampshire! Let the fun begin!
2. If justice should be pursued always all the time, injustice should be avoided always all the time.
