Letters between mum and dad in Central America (6)
I believe the answer is:
panama
'in central america' is the definition.
('Panama' is part of 'central america')
'letters between mum and dad' is the wordplay.
'letters between' becomes 'na' (I can't justify this - if you can you should give a lot more credence to this answer).
'mum' becomes 'ma' (ma can mean mother).
'and' is a charade indicator (letters next to each other).
'dad' becomes 'pa' (both can mean one's father).
'na'+'ma'='nama'
'nama' after 'pa' is 'PANAMA'.
Can you help me to learn more?
(Other definitions for panama that I've seen before include "What may be seen overhead" , "isthmus" , "'Country, canal and hat (6)'" , "American canal or kind of hat" , "Headgear for a canal" .)
