glow: [OE] Glow comes ultimately from Indo- European *ghlō-, in which the ghl- seems originally to have had some sort of symbolic function, as if directly representing the notion of ‘brightness, shining’ in speech. Its Germanic descendant *glō- produced German glühen, Dutch gloeien, and Swedish glöda (all meaning ‘glow’) as well as English glow and probably also glower [16]. => glower[glow etymology, glow origin, 英语词源]
