insolently

The word "insolently" originates from the Latin adjective insolens, which itself is a compound of the negative prefix in- ("not") and solens, the present participle of the verb solere ("to be accustomed"). The literal sense of insolens was therefore "unaccustomed," which evolved to mean "unusual, excessive, immoderate," and finally settled on the meaning of "haughty, arrogant, contemptuous." This semantic shift reflects the idea that behavior which deviates drastically from customary norms of respect is perceived as arrogant and disrespectful. The adverbial suffix -ly, of Germanic origin, was later attached to form the modern English adverb describing the manner of such behavior.
