New text, Raja hid (5)
I believe the answer is:
extra
'new' is the definition.
(thesaurus)
'text raja hid' is the wordplay.
'hid' says the answer is hidden in the clue (I've seen 'hide' mean this).
'EXTRA' can be found hidden inside 'text raja'.
(Other definitions for extra that I've seen before include "One playing small part" , "An additional thing" , "Additional or supplementary" , "Surplus to requirements" , "An increased amount" .)
