Be inclined to choke with love inside (5)
I believe the answer is:
stoop
'be inclined' is the definition.
Although both the answer and definition are verbs in their base form, I don't see how they can define each other.
'choke with love inside' is the wordplay.
'choke with' becomes 'stop' (I can't explain this - if you can you should give a lot more credence to this answer).
'love' becomes 'o' (love means zero in tennis).
'inside' means one lot of letters goes inside another.
'stop' enclosing 'o' is 'STOOP'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for stoop that I've seen before include "Bend the top half of the body" , "Lower one's standards" , "Bend the body forwards" , "Hunch" , "Bend forward from the waist" .)
