Indian's cart excellent on Ganges' bridges (5)
I believe the answer is:
tonga
'indian's' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'cart excellent on ganges' bridges' is the wordplay.
'TONGA' is hidden within the letters.
But, I'm uncertain how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for tonga that I've seen before include "group of Pacific islands" , "Do a bad tango in the Pacific archipelago" , "Two-wheeled Indian vehicle" , "SW Pacific monarchy" , "The Friendly Islands" .)
