Bear with a blemish following us around (7)
I believe the answer is:
sustain
'bear with' is the definition.
(thesaurus)
'a blemish following us around' is the wordplay.
'a blemish' becomes 'stain' (stain is a kind of blemish).
'following' means one lot of letters go next to another.
'around' shows that the letters should be reversed in order.
'us' written backwards gives 'su'.
'stain' after 'su' is 'SUSTAIN'.
(Other definitions for sustain that I've seen before include "Prolong, support" , "Endure" , "Keep alive" , "Carry" , "Nurish" .)
