Issue I'd sorted out to keep gelding's head in front (8)
I believe the answer is:
disguise
'front' is the definition.
(I've seen this before)
'issue i'd sorted out to keep gelding's head' is the wordplay.
'sorted out' is an anagram indicator.
'to keep' means one lot of letters goes inside another.
'head' suggests taking the first letters.
The initial letter of 'gelding' is 'g'.
'issue'+'id'='issueid'
'issueid' anagrammed gives 'disuise'.
'disuise' enclosing 'g' is 'DISGUISE'.
'in' is the link.
(Other definitions for disguise that I've seen before include "Conceal (one's identity)" , "Pretence" , "Camouflage, mask" , "Conceal (a feeling)" , "Make unrecognizable" .)
