IPA: /ˌæn.tɪˈlɒdʒ.i/
KK: /æntɪˈlɒdʒi/
A situation where two related ideas or terms contradict each other, often leading to confusion or inconsistency.
The author's argument was weakened by an antilogy that contradicted his main point.
Antilogy is formed from "anti-" (meaning against) and "logia" (from Greek "logia", meaning discourse or study). The word refers to a discourse that presents contradictory or opposing ideas.
Think of 'against' ('anti-') and 'discourse' ('logia') to remember that antilogy refers to a discourse that contains opposing ideas.
