Etymology of brightened
Brightened derives from brighten, formed from the Old English adjective 'beorht' (modern 'bright'), which traces back through Proto-Germanic *berhtaz to the Proto-Indo-European root *bhereg-, meaning 'to shine' or 'gleam'. This ancient root also gave rise to Latin-related cognates such as 'brilliant', via Latin 'beryllus' and Greek 'bery llos' for the gemstone beryl, whose sparkle embodied the same idea of shining light. The verb brighten emerged in English during the Middle English period, combining the adjective with the common verb-forming suffix -en.
