词源

Unadapted borrowing from German Urstromtal, from ur- (prefix meaning ‘original; primitive’) + Strom (“large river; stream”) (ultimately from Proto-Indo-European *srew- (“to flow; stream”)) + Tal (“valley”) (ultimate etymology uncertain, possibly from Proto-Indo-European *dʰól(h₂)os).
The plural form urstromtäler is also an unadapted borrowing from German Urstromtäler.
