What is odi et amo?

"Odi et amo" is a Latin phrase which translates to "I hate and I love." It is taken from the love elegy "Catullus 85" by the Roman poet Catullus. In this poem, Catullus expresses the conflicting emotions of love and hate that he feels towards his lover, which are often intertwined and indistinguishable. The phrase has since become a popular and enduring expression of the complexities and contradictions of human emotions.
