- brosdaich
- stir up, Irish brosduighim, Early Irish brostugud, inciting. The word is from the root bros-, in brosdo- of brod, q.v., being here bros-to-, which become brosso-, and later reverts to brost, brosd, or remains as in brosnaich. Stokes says it is founded on Low Latin brosdus, brusdus, broidery, "done by a needle", or brosd, which is of Teutonic origin and cognate with Gaelic brod, already given as the root. Hence brosgadh, stimulation, etc. The Irish brosna, Old Irish brosne, faggot, may be hence; the root bhrud, discussed under ++bronn, has also been suggested.
