Language elevated in sublimation (5)
I believe the answer is:
tamil
'language' is the definition.
(Tamil is an example)
'elevated in sublimation' is the wordplay.
'elevated' says the letters should be written backwards.
'in' indicates a hidden word.
'limat' can be found hidden inside 'sublimation'.
'limat' back-to-front is 'TAMIL'.
(Other definitions for tamil that I've seen before include "Perhaps Indian" , "S. India/Sri Lankan person, tongue" , "Asian language" , "Language of southern India and Sri Lanka" , "South Indian people or language" .)
