Twilight: the half-light between day and night
‘Twilight’ joins ‘two’ and ‘light’ to name the half-light between day and night. From Old English twi-lyht, it shares roots with ‘twin’ and ‘lucid’. Its Romance cousin crepusculum gave French ‘crépuscule’ and Italian ‘crepuscolo’. Across Europe, twilight glows through words of dimness, doubling, and fading.
