Rise above wild canters with reindeer, essentially (9)
I believe the answer is:
transcend
'rise above' is the definition.
(thesaurus)
'wild canters with reindeer essentially' is the wordplay.
'wild' indicates anagramming the letters.
'with' means one lot of letters go next to another.
'essentially' says to take the centre.
The middle letters of 'reindeer' are 'nd'.
'canters' with letters rearranged gives 'transce'.
'transce'+'nd'='TRANSCEND'
(Other definitions for transcend that I've seen before include "Surpass (an achievement)" , "exceed?" , "Go beyond, surpass" .)
