The Partite Lemma is a key piece in structural Ramsey theory. We give a purely category theoretic take on the Partite Lemma and establishes the canonicity of the object in the Partite Lemma. Additionally, the categorical point of view allows us to unify the direct Partite Lemma with the dual Paritite Lemma.
