Subservient in particular rank -- nothing gets overlooked (10)
I believe the answer is:
respectful
'subservient' is the definition.
(showing respect)
'particular rank nothing gets overlooked' is the wordplay.
'particular' becomes 'respect' (in that particular or in that respect).
'rank' becomes 'foul' (both can mean rotten or disgusting).
'nothing' becomes 'O' (looks like zero - 0).
'gets overlooked' is a deletion indicator.
'foul' with 'o' taken away is 'ful'.
'respect'+'ful'='RESPECTFUL'
'in' is the link.
(Other definitions for respectful that I've seen before include "Showing due regard for others" , "Showing due deference" .)
