Please get her to translate this minimalist language (12)
I believe the answer is:
telegraphese
'this minimalist language' is the definition.
(term for the basic language used in telegrams)
'please get her to translate' is the wordplay.
'to translate' indicates an anagram.
'please'+'get'+'her'='pleasegether'
'pleasegether' anagrammed gives 'TELEGRAPHESE'.
(Other definitions for telegraphese that I've seen before include "Potted jargon" , "terse jargon" .)
