Drunk in Rome, swallowing extremes of vino? One'd swallow everything (8)
I believe the answer is:
omnivore
'one'd swallow everything' is the definition.
I can't tell whether this definition defines the answer.
'drunk in rome swallowing extremes of vino?' is the wordplay.
'drunk' indicates an anagram.
'swallowing' indicates putting letters inside.
'extremes of' suggests removing the centre (only the letters at the extremes of the word).
'vino' with its centre removed is 'vo'.
'in'+'rome'='inrome'
'inrome' anagrammed gives 'omnire'.
'omnire' going around 'vo' is 'OMNIVORE'.
Can you help me to learn more?
(Other definitions for omnivore that I've seen before include "One eating anything" , "Animal that eats any type of food" , "It will eat anything, animal or vegetable" , "who'll swallow anything?" , "One who eats all kinds of foods" .)
