How would you describe a dour official?

A dour official is best described as ill-tempered, which conveys a sense of being stern, unfriendly, or moody. The term "dour" itself often refers to a demeanor that lacks warmth or cheerfulness, suggesting that the official is serious or even stern in nature. This description aligns precisely with the concept of being ill-tempered, as such individuals typically do not exhibit a friendly or approachable attitude.

In contrast, the other options describe characteristics that are essentially the opposite of what "dour" implies. Being friendly or optimistic suggests a positive disposition towards others, while being generous indicates a willingness to give and share, all of which are contrary to the typically stern and unyielding nature described by "dour." Thus, recognizing the nuances of these terms helps clarify why ill-tempered is the most suitable descriptor for a dour official.
