strath

English

WOTD – 30 November 2025

Etymology

Borrowed from Irish srath and Scottish Gaelic srath (wide, flat river valley, strath; floor of river valley; river meadow), both from Old Irish srath (grass, sward; river valley; floor of river valley; river meadow), from Proto-Celtic *stratos (valley),[1] from Proto-Indo-European *str̥h₃tós (spread; stretched, adjective), from *sterh₃- (to extend, spread, stretch out). The meaning was likely influenced by a Cumbric/Pictish cognate; compare Welsh ystrad. Doublet of stratus.

Usage notes

The word is found in Scottish place names. As it is usually the first element of such names (for example, the ones listed in the “Related terms” section below), these names are chiefly derived from Scottish Gaelic, or in some early cases in a Brythonic language or Pictish, rather than formed in English.[1]
