Etymology

twilight = twi<two/half> + light<illumination>

  • twi<two/half>: From Old English twi-, meaning "two" or "half," seen in words like twice or twine. Here, it suggests a duality (day/night) or partial state.
  • light<illumination>: From Old English lēoht, referring to brightness. Combined, the word literally means "half-light."

Etymology Origin:
The word twilight emerged in Middle English (14th century) from Old English twi- and lēoht, capturing the transitional light between day and night. The "twi-" prefix reflects the duality of the phenomenon—neither full daylight nor complete darkness. Over time, it gained metaphorical uses to describe transitional or fading states, mirroring its literal meaning.
