rilling

Verb

rill (third-person singular simple present rills, present participle rilling, simple past and past participle rilled)

1. To trickle, pour, or run like a small stream.
   • And fainter, finer, trickle far
     To where the listening uplands are;
     To pause—then from his gurgling bill
     Let the warbled sweetness rill,
     And down the welkin, gushing free,
     Hark the molten melody;1862, Gerard Manley Hopkins, Il Mystico, 81-86
