stream (English)

Where does "stream" come from?

The word 'stream' traces its origins to the Proto-Indo-European root *srew-, meaning 'to flow.' It evolved through Proto-Germanic as *straumaz and Old English as strēam, eventually reaching Middle English before becoming the modern English term we use today. This ancient concept of flowing water has persisted through millennia, sharing deep linguistic ties with diverse words like the Greek rheuma and the Lithuanian srovė.
