Barman on holiday island could be mistaken for a guinea pig (6)
I believe the answer is:
agouti
'guinea pig' is the definition.
The definition and answer can be both animals as well as being singular nouns.
Maybe there's a link between them I don't understand?
'barman on holiday island could be mistaken for a' is the wordplay.
I cannot quite see how this works, but
'island' could be 'i' and 'i' is found in the answer.
'be' could be 'go' (going is a kind of being) and 'go' is found within the answer.
'a' is within the answer.
The remaining letters 'ut' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for agouti that I've seen before include "Caribbean rodent" , "Guinea pig-like rodent" , "animal" , "S.Amer. rodent" , "South American rodent" .)
