Definition of the word brim

The word "brim" has a fascinating history. It originated from Old English and Middle English, where it was spelled "borm" or "brum". The word is related to the Old English word "biorm", which means "edge" or "border". This is likely because the brim of a hat or a vessel was considered the outer edge or border of the object. Over time, the spelling evolved to "brim" and the meaning expanded to include the edge of a cup, hat, or other objects. Today, we use "brim" to refer to the edge of a hat, the rim of a cup, or even the edge of a situation (as in "on the brink of" something). That's the brief story of the word "brim"!
