A drink dad gets out of the tin, maybe (5)
I believe the answer is:
pinta
'a drink' is the definition.
(I've seen this before)
'gets out of the tin maybe' is the wordplay.
'gets' becomes 'pa' (I am not sure about this - if you are sure you should believe this answer much more).
'out of' indicates putting letters inside (some letters on the outside of others).
'maybe' indicates an anagram.
'tin' is an anagram of 'int'.
'pa' placed around 'int' is 'PINTA'.
'dad' acts as a link.
This may not be correct. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for pinta that I've seen before include "vessel for Columbus?" , "Columbus's ship - some milk!" , "drink" , "early delivery?" , "Bottle of milk" .)
