Pair consuming beer, two shakes and Italian port (7)
I believe the answer is:
palermo
'italian port' is the definition.
'palermo' can be an answer for 'port' (I've seen this before). I'm not sure about the 'italian' bit.
'pair consuming beer two shakes' is the wordplay.
'pair' becomes 'pr' (abbreviation).
'consuming' is an insertion indicator.
'beer' becomes 'ale' (type of beer).
'two shakes' becomes 'mo' (I can't explain this - if you can you should give a lot more credence to this answer).
'pr' enclosing 'ale' is 'paler'.
'paler'+'mo'='PALERMO'
'and' is the link.
Can you help me to learn more?
(Other definitions for palermo that I've seen before include "ity of Italy" , "Sicilian city" , "Sicilian capital" , "Capital city of Sicily" , "Sicilian port" .)
