Here's why:
* Usage: "Aloof" is often used in more formal writing and speech, particularly when describing someone's behavior or attitude. It implies a more deliberate and conscious distance from others.
* Connotation: "Aloof" has a slightly negative connotation, suggesting a lack of engagement or warmth. This makes it a less casual word.
Example:
* Informal: "He was really distant and didn't talk much."
* Formal: "She maintained an aloof demeanor throughout the meeting."
In summary: While not strictly formal, "aloof" is a more elevated and nuanced word than some of its synonyms, making it appropriate for formal situations but also suitable for everyday use.
