What is a hat nib?

[untonuggan]

My grandmother is 92 and lives in Yorkshire, United Kingdom. She's knitted for me for years. Now that she's found out I knit (when she can't anymore due to arthritis) she has requested a hat. I got the request through my mother, so some of this information is second-hand.

Apparently, she wants a hat with a "nib."

I do not know exactly what a nib is, but that could be due to differences in age/location/dialect/etc. I was hoping someone here knew what a hat nib was. My mom thinks it might be some sort of brim, but I'm not sure. If you have suggestions of patterns on ravelry, that would be great too.

Thanks for any help!
