I get in drunk and start fire (6)
I believe the answer is:
ignite
'start fire' is the definition.
'ignite' can be an answer for 'fire' (I've seen this before). I am unsure of the 'start' bit.
'i get in drunk' is the wordplay.
'drunk' indicates anagramming the letters.
'get'+'in'='getin'
'getin' with letters rearranged gives 'gnite'.
'i'+'gnite'='IGNITE'
'and' is the link.
Can you help me to learn more?
(Other definitions for ignite that I've seen before include "Torch" , "Spark off" , "Put a match to" , "Kindle Fire" , "Cause to start burning" .)
