Land back on long branch (4)
I believe the answer is:
wing
'branch' is the definition.
(thesaurus)
'land back on long' is the wordplay.
'land' becomes 'win'.
'back on' indicates one should take the final letters (the letter at the back).
The last letter of 'long' is 'g'.
'win'+'g'='WING'
(Other definitions for wing that I've seen before include "Aircraft's support" , "Limb - faction" , "Faction; annexe" , "Take . . . . to fly away (4)" , "Wound, but not fatally" .)
