_Brash_--often _bresh_--in the sense of refuse boughs of trees, is only another form of _brush_; the two are used as one word by the people.

_Brash_ in the sense of brittle has no conscious connection with the noun in popular usage, but it is accounted by the people the same word as _brash_ in the sense of rash or impetuous.

The suggestion in the Century Dictionary that the words spelled _brash_ are of modern formation violates the soundest canon of antiquarian research, which is that a word phrase or custom widely diffused among plain or rustic people is of necessity of ancient origin.
Now _brash_, the adjective, exists in both senses in two or three of the most widely separated dialects of the United States, and hence must have come from England.

Indeed, it appears in Wright's Dictionary of Provincial English in precisely the sense it has in the text.].
