Trickled
I believe the answer is:
seeped
'trickled' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for seeped that I've seen before include "Exuded" , "Leaked gradually through a small opening" , "Sweated" , "Oozed or percolated" , "Oozed slowly out" .)
