It gives the chop to article in intelligent setting (7)
I believe the answer is:
cleaver
'it gives the chop to article' is the definition.
The definition suggests a singular noun which matches the answer.
'in intelligent setting' is the wordplay.
'in' means one lot of letters goes inside another.
'intelligent' becomes 'clever' (similar in meaning).
'setting' becomes 'a' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'clever' placed around 'a' is 'CLEAVER'.
Can you help me to learn more?
(Other definitions for cleaver that I've seen before include "Butcher's knife" , "A butcher may use it" , "dangerous object?" , "Hatchet for chopping meat" , "Meat axe" .)
