What term refers to a strict or harsh demeanor in behavior?

The term that captures a strict or harsh demeanor in behavior is often associated with characteristics that reflect firmness or a lack of leniency. In this context, choices such as severity, strictness, and sternness all effectively convey similar meanings related to a rigid or uncompromising approach to behavior or discipline.

Severity refers to the harshness or intensity of behavior, particularly in judgment or discipline. It can imply a level of seriousness that leaves little room for leniency or forgiveness.

Strictness indicates a firm adherence to rules or standards, emphasizing a no-nonsense approach that does not tolerate deviations from established norms.

Integrating these nuances provides a more comprehensive view of what it means to exhibit a strict or harsh demeanor.
