Language used in Berlin government (5)

I believe the answer is:

lingo

'language' is the definition.
(lingo is a kind of language)

'in berlin government' is the wordplay.
'in' says the answer is hidden in the clue.
'LINGO' can be found hidden inside 'berlin government'.

'used' is the link.

(Other definitions for lingo that I've seen before include "Log in (anag.)" , "Johnny Foreigner speaks one" , "Language (informally)" , "Tongue" , "local dialect" .)

I've seen this clue in The Independent.
