Brief conversation after case in Tanzania, for example (11,4)

Ross

I believe the answer is:

portmanteau word

I'm a little stuck... Click here to teach me more about this clue!

'example' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Maybe there's a link between them I don't understand?

'brief conversation after case in tanzania' is the wordplay.
I cannot really understand how this works, but
'conversation' could be 'word' (as in having a word with someone) and 'word' is found in the answer.
'case' could be 'portmanteau' (portmanteau is a kind of case) and 'portmanteau' is found within the answer.
This accounts for all the letters.
This explanation may well be incorrect...

'for' acts as a link.

Can you help me to learn more?

(Other definitions for portmanteau word that I've seen before include "motel, perhaps" , "E.g. biopic" , "Televangelist perhaps" , "fanzine, for one" .)
