Difference Between Erotic and ErraticErotic means suggestive of sexual interest or desire: “The ancient temples in India show gods and goddesses in erotic postures.”
Erratic, on the other hand, means characterized by no fixed course of action or purpose: “A person with erratic mood swings can be quite dangerous.”

The infamous and often erotic behavior of the artist led the public to sense an erratic pattern to the production of his paintings.
