immodestly

The word "immodestly" is built upon the core Latin adjective "modestus," which itself derives from "modus," meaning "measure, manner, or limit." The prefix "im-" is an assimilated form of the Latin "in-," meaning "not," which negates the core meaning. Thus, the literal construction yields "not keeping within proper measure." The adverbial suffix "-ly," of Germanic origin, transforms this quality into a descriptor of manner. Over time, the concept of exceeding proper measure evolved specifically to denote a lack of humility or restraint, particularly regarding one's abilities or importance, giving us the modern sense of behaving in a boastful or overly forward way.
