obtuse

Obtuse is a formal adjective that describes someone who is unable to think clearly or understand what is obvious or simple. It can also suggest a refusal to see something apparent to others or a willful ignorance of the real facts of a situation. Additionally, obtuse can describe something that is difficult to understand due to its unclear or imprecise nature. The word has multiple meanings, including describing a geometric angle greater than 90 degrees but less than 180 degrees. It can also describe a leaf that is rounded at its free end. The word obtuse originates from the Latin word obtusus, meaning "dull" or "blunt." In everyday language, if someone asks if you're being obtuse, it's not a compliment. Obtuse can also mean "hard to comprehend," often applied to unclear speech or writing. This sense of the word may have developed due to the influence of similar-sounding words like abstruse and obscure.
