Section of text? Rather more (5)
I believe the answer is:
extra
'more' is the definition.
(thesaurus)
'section of text? rather' is the wordplay.
'section of' says the answer is hidden in the clue.
'EXTRA' can be found hidden inside 'text rather'.
(Other definitions for extra that I've seen before include "Minor actors in crowd scenes" , "comes to 16 [TEST MATCH]" , "small-time actor" , "Crowd-scene actor" , "leg bye perhaps" .)
