Fairy Liquid initially taken from bottle (4)
I believe the answer is:
puck
'fairy' is the definition.
(puck is a kind of fairy)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for puck that I've seen before include "One of 5 [FAIRIES]" , "played with on ice" , "Mischievous character" , "In summer, one dreamt" , "Ice hockey disc - Shakespeare character" .)
