Respect is introduced to English backs (6)
I believe the answer is:
esteem
'respect' is the definition.
(I know that respect can be written as esteem)
'is introduced to english backs' is the wordplay.
'is introduced to' becomes 'meets' (I've seen this in another clue).
'english' becomes 'e' (abbreviation).
'backs' shows that the letters should be reversed in order.
'meets'+'e'='meetse'
'meetse' written backwards gives 'ESTEEM'.
(Other definitions for esteem that I've seen before include "Think highly of, have regard for" , "Respect, admire" , "judge" , "Honour - regard" , "Good opinion" .)
