American in Havana going off about air terminal (6)
I believe the answer is:
gringo
'american in havana' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'going off about air terminal' is the wordplay.
'off' indicates an anagram.
'about' is an insertion indicator.
'terminal' suggests the final letters (terminal refers to the end).
The final letter of 'air' is 'r'.
'going' with letters rearranged gives 'gingo'.
'gingo' enclosing 'r' is 'GRINGO'.
Can you help me to learn more?
(Other definitions for gringo that I've seen before include "Non-Spanish speaker" , "Latin-American term for English speaker" , "What the Mexican calls the American" , "English-speaker abroad" .)
