Gift yours truly intended without a misgiving (12)
I believe the answer is:
presentiment
'misgiving' is the definition.
(thesaurus)
'gift yours truly intended without a' is the wordplay.
'gift' becomes 'present' (present is a kind of gift).
'yours truly' becomes 'i'.
'intended' becomes 'meant' ('mean' can be a synonym of 'intend').
'without' is a deletion indicator.
'meant' with 'a' removed is 'ment'.
'present'+'i'+'ment'='PRESENTIMENT'
(Other definitions for presentiment that I've seen before include "Feeling of apprehension" , "bad feeling" , "An intuitive feeling" , "Intuitive foreboding" .)
