What does hirsute specifically refer to?

Hirsute specifically refers to having dense or thick hair. The term is often used in a biological context to describe organisms, particularly mammals, that possess an abundance of hair or fur. It can also be applied to describe individuals who are unusually hairy. The root of the word, derived from Latin, directly ties to hairiness, reinforcing the connection to having a lot of hair. This clarity about the term emphasizes why it specifically relates to hair density rather than skin characteristics, personality traits, or attitudes, which are represented by the other options.
