Ventpeg to leave in dilapidated pits (6)
I believe the answer is:
spigot
'ventpeg' is the definition.
I can't tell whether this defines the answer.
'leave in dilapidated pits' is the wordplay.
'leave' becomes 'go' (to go is to depart or leave).
'in' is an insertion indicator.
'dilapidated' indicates an anagram.
'pits' anagrammed gives 'spit'.
'go' placed into 'spit' is 'SPIGOT'.
'to' is the link.
Can you help me to learn more?
(Other definitions for spigot that I've seen before include "Small peg or plug" , "Got sip? (Anag)" , "Peg to seal vent in cask" , "Peg that stops the vent of a cask" , "Device for stopping" .)
