Name missing from gift arranged in advance (6)
I believe the answer is:
preset
'arranged in advance' is the definition.
(I've seen this in another clue)
'name missing from gift' is the wordplay.
'name' becomes 'n' (common abbreviation e.g. on forms).
'missing from' is a deletion indicator.
'gift' becomes 'present' (synonyms).
'present' with 'n' taken out is 'PRESET'.
(Other definitions for preset that I've seen before include "Pester (anag.)" , "ready in advance" , "Determined beforehand" , "Initially fixed value or control" , "Adjust (control) before use" .)
