  1. A very small brook; a streamlet.
    • 1797, Samuel Taylor Coleridge, Kubla Khan:
      So twice five miles of fertile ground
      With walls and towers were girdled round :
      And there were gardens bright with sinuous rills,
      Where blossomed many an incense-bearing tree ;
      And here were forests ancient as the hills,
      Enfolding sunny spots of greenery.
