Over and above some complex trauma (5)

I believe the answer is:

extra

'over and above' is the definition.
(thesaurus)

'some complex trauma' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'EXTRA' is hidden within 'complex trauma'.

(Other definitions for extra that I've seen before include "small-time actor" , "Score not made by 34 [CRICKETER]" , "Minor actor in crowd scene" , "An additional thing" , "Surplus to requirements" .)

I've seen this clue in the Irish Times and the Irish Times (Crosaire).
