'alpenglow' originates from German, specifically the word 'Alpenglühen,' where 'Alpen' meant 'Alps' and 'glühen' meant 'to glow.'

'Alpenglühen' transformed into the English word 'alpenglow' and retained its meaning related to the glow on mountain peaks.

Initially, it meant 'the glow on the Alps,' but over time it evolved to refer to any mountain glow at sunset or sunrise.
