Irish city's ship's company that gets stuck into the vino (9)
I believe the answer is:
corkscrew
'irish city's ship's company that gets stuck into the vino' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'irish city's ship's company' is the wordplay.
'irish city's' becomes 'Cork's'.
'ship's company' becomes 'crew' (I've seen this before).
'corks'+'crew'='CORKSCREW'
Can you help me to learn more?
(Other definitions for corkscrew that I've seen before include "Bottle-opener" , "Device used to get at red" , "This might help one who gets in the drink" , "Move in a spiral manner" , "Spiral device for wine lovers" .)
