obtused

Obtuse refers to something that is dull or blunt, lacking sharpness or acuteness. In geometry, an obtuse angle is one that measures greater than 90 degrees and less than 180 degrees. This type of angle is characterized by its lack of sharpness, with the two lines or planes that form the angle being relatively far apart.

In everyday language, obtuse is often used to describe a blunt or insensitive remark or action. For example, saying something that is tactless or thoughtless might be referred to as an "obtuse comment". In this context, the term implies a lack of understanding or consideration for the feelings or perspectives of others.

In psychology, the term obtuse is sometimes used to describe a person or their behavior, implying a lack of awareness or insight. This can manifest in a variety of ways, such as a failure to understand social cues or a tendency to act impulsively without considering the consequences.

The antonym of obtuse is acute, which describes something that is sharp or pointed, with a clear and precise understanding. The term obtuse is also related to the Latin for "dull", which reinforces its meaning as a lack of sharpness or acuteness.

Overall, the term obtuse has a range of meanings and applications, from geometry to everyday language and psychology. Its core implication is a lack of sharpness, insight, or awareness.
