gruff

What does "gruff" mean?
The word "gruff" describes someone who sounds rough, low-pitched, and perhaps a bit abrupt or unfriendly when they speak. Imagine an old, tired sea captain or a grumpy character who doesn't like small talk; their voice sounds gravelly and their manner seems short, though it doesn't necessarily mean they are truly mean-spirited. You will often hear this used to describe a person's voice or their general demeanor. It implies a lack of polish or warmth, but it can also be used affectionately for someone who is "tough on the outside, soft on the inside." It is a common descriptor for authority figures or characters in stories who are stern but ultimately harmless.
