Am put in the shade - terribly abashed (7)
I believe the answer is:
ashamed
'abashed' is the definition.
(I've seen this before)
'am put in the shade terribly' is the wordplay.
'put in' indicates putting letters inside.
'terribly' is an anagram indicator.
'shade' with letters rearranged gives 'ashed'.
'am' placed into 'ashed' is 'ASHAMED'.
(Other definitions for ashamed that I've seen before include "hanging his head" , "Having painful regret for behaviour" , "Sorry" , "Feeling guilty" , "Feeling remorse and contrition" .)
