1. fire, n. [fahyuh r, fīr]
-Appropriately enough for one of the mainsprings of human civilization, the word fire is widespread amongst Indo-European languages (although it is only one of two competing ‘fire’ strands, the other being represented by English ignite.) Among its relatives are Greek pur (where we get English pyre, pyrotechnic), Czech pýr ‘embers,’ Armenian hūr, Dutch vuur, German Feuer, and Hittite pahhur, pointing back to a prehistoric Indo-European pūr. Our English fire was written in Old English as fýr and is specifically West Germanic in origin. Its approximate assimilation time dates to before 900 CE.
2. wind, n. [wind, wĭnd]
-English has three distinct words wind, but we’ll be focusing on the noun ‘moving air’ for now. This wind came to us before 900 CE from a prehistoric Germanic windaz, which also produced German and Dutch wind and Swedish and Danish vind. This in turn went back to Indo-European went-, whose other descendants include Latin ventus (source of English vent, ventilate, etc) and Welsh gwynt. And went- itself was derived from the base we- ‘blow,’ source of Greek aētēs ‘wind’ and āēr ‘air,’ Sanskrit vātas ‘wind’ and Russian vejat’ ‘blow.’
