It’s spoken in urban Tunbridge Wells (5)

I believe the answer is:

bantu

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

'it's spoken' is the definition.
I can't tell whether this defines the answer.

'in urban tunbridge wells' is the wordplay.
'in' indicates a hidden word.
'BANTU' is hidden in the letters of 'urban tunbridge wells'.

Can you help me to learn more?

(Other definitions for bantu that I've seen before include "Group of Niger-Congo languages" , "A language and people of Africa" , "Group of languages including Swahili and Xhosa" , "South African" , "Native African language" .)

I've seen this clue in the Evening Standard.
