Wrinkled, lacking credit but comforted (5)
I believe the answer is:
eased
'comforted' is the definition.
(easing is a kind of comforting)
'wrinkled lacking credit' is the wordplay.
'wrinkled' becomes 'creased' ('crease' can be a synonym of 'wrinkle').
'lacking' indicates named letters should be taken away.
'credit' becomes 'cr'.
'creased' with 'cr' removed is 'EASED'.
'but' acts as a link.
(Other definitions for eased that I've seen before include "Made less hard" , "Made less difficult or trying" , "Moved carefully" , "relented" , "Given relief" .)
