Going against or opposite to nature; unnatural or contrary to natural law or order.
From Latin 'contra-' (against) + 'naturalis' (of nature). A philosophical term used from medieval times onward to describe things that violate natural principles.
Medieval theologians used 'contranatural' to describe acts against 'natural law'—like how they thought same-sex relationships were contranatural. The word reveals more about medieval assumptions than about nature itself.
