US possession of Antigua, maybe (4)
I believe the answer is:
guam
'us possession' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'of antigua maybe' is the wordplay.
'of' indicates a hidden word.
'GUAM' is hidden within 'antigua maybe'.
Can you help me to learn more?
(Other definitions for guam that I've seen before include "Largest of the Mariana Islands" , "North Pacific island, base for the US navy and air force" , "US island east of the Philippines" , "place in the Marianas" , "Island in the West Pacific" .)
