Yet it's a misplaced feeling of gratification (7)
I believe the answer is:
satiety
'gratification' is the definition.
(I know that satiety is a type of gratification)
'yet it's a misplaced' is the wordplay.
'misplaced' is an anagram indicator (letters in the wrong places).
'yet'+'its'+'a'='yetitsa'
'yetitsa' is an anagram of 'SATIETY'.
'feeling of' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for satiety that I've seen before include "Boredom" , "Having enough" , "What follows overindulgence" , "Repletion" , "Feeling of fullness" .)
