Year in poverty after horse is worn-out (9)
I believe the answer is:
hackneyed
'worn-out' is the definition.
(thesaurus)
'year in poverty after horse' is the wordplay.
'year' becomes 'y'.
'in' indicates putting letters inside.
'poverty' becomes 'need' (I've seen this before).
'after' is a charade indicator (letters next to each other).
'horse' becomes 'hack' (hack is a kind of horse**).
'y' inserted inside 'need' is 'neyed'.
'neyed' put after 'hack' is 'HACKNEYED'.
'is' is the link.
(Other definitions for hackneyed that I've seen before include "Trite (expression)" , "using familiar phraseology?" , "Stereotyped" , "pedestrian" , "Overfamiliar through overuse" .)
