Sorry, seeing quote put up after course (8)
I believe the answer is:
pathetic
'sorry' is the definition.
(thesaurus)
'quote put up after course' is the wordplay.
'quote' becomes 'cite' ('cite' can be a synonym of 'quote').
'put up' is a reversal indicator.
'after' is a charade indicator (letters next to each other).
'course' becomes 'path' ('path' can be a synonym of 'course'**).
'cite' back-to-front is 'etic'.
'etic' put after 'path' is 'PATHETIC'.
'seeing' is the link.
(Other definitions for pathetic that I've seen before include "Touching and pitiful" , "Sadly inadequate" , "Wretched" , "Feeble; inspiring pity" , "arousing contempt" .)
