No reason to be worried about end of term feature (5,4)
I believe the answer is:
roman nose
'feature' is the definition.
(I have seen 'outstanding feature' mean 'roman nose' so perhaps 'feature' could also mean 'roman nose')
'no reason to be worried about end of term' is the wordplay.
'to be worried' is an anagram indicator.
'about' indicates putting letters inside.
'end of' suggests the final letters.
The final letter of 'term' is 'm'.
'no'+'reason'='noreason'
'noreason' with letters rearranged gives 'roannose'.
'roannose' going around 'm' is 'ROMAN NOSE'.
(Other definitions for roman nose that I've seen before include "outstanding feature" , "personal feature" , "prominent Italian feature" , "feature with bridge" .)
