Help to dig where a flier drinks? (7)
I believe the answer is:
crowbar
'help to dig' is the definition.
(a crowbar might be used for digging)
'a flier drinks?' is the wordplay.
'a flier' becomes 'crow' (crow is a kind of birdanimal).
'drinks?' becomes 'bar' (I can't explain this - if you can you should give a lot more credence to this answer).
'crow'+'bar'='CROWBAR'
'where' acts as a link.
Can you help me to learn more?
(Other definitions for crowbar that I've seen before include "Purchase may be obtained from this" , "The means to get leverage" , "Strong iron rod used as lever" , "Jemmy" , "Metal rod used as a lever" .)
