Translation according to P. W. Joyce:
Sroove in Galway, Roscommon, and Sligo; Srubh or Sruibh, a stream. Srubh and Sruth, both meaning stream (vol. i. p. 457), are modifications from one root.
Sruth occurs pretty often in names, and its various derivatives, especially the diminutives, have also impressed themselves extensively on the nomenclature of the country. In its simple form it gives names to Srue in Galway; to Shruh in Waterford; and to Shrough in Tipperary; Ballystrew near Downpatrick is the town of the stream.
