Here's a breakdown:
* Unruffled: Meaning smooth, calm, not agitated or disturbed.
* Brow: Refers to the forehead, and in this context, the way it looks.
In essence, an unruffled brow implies that a person is not showing any outward signs of stress or worry. They appear serene and collected, even in challenging situations.
Examples:
* "Despite the chaos around him, he remained calm with an unruffled brow."
* "She faced the difficult task with an unruffled brow, showing her confidence and composure."
The opposite of an unruffled brow would be a furrowed brow, which implies worry, concern, or anger.
