Place in Panama: (5)
I believe the answer is:
colon
This clue could be a double definition.
'place' is the first definition.
The answer and definition can be both related to communication as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'in panama' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for colon that I've seen before include "City at the Caribbean entrance to the Panama Canal" , "Part of body; two dots" , "Stop (on the inside!)" , "Punctuate part of the large intestine" , "Panamanian port" .)
