Meretriciously → It is formed from "meretricius" (from Latin, meaning of or pertaining to a prostitute) and the suffix "-ly" (meaning in a manner). The word describes behavior that is characteristic of or resembles that of a prostitute, often implying something that is gaudy or superficial.
Think of the Latin root 'meretricius' which relates to a prostitute, and remember that 'meretriciously' describes actions done in a superficial or gaudy manner, similar to that behavior.
