Loveless pair become confused in senseless talk (7)
I believe the answer is:
twaddle
'senseless talk' is the definition.
(I've seen this before)
'loveless pair become confused' is the wordplay.
'loveless pair' becomes 'tw' (I am not sure about this - if you are sure you should believe this answer much more).
'become confused' becomes 'addle' (I've seen this before).
'tw'+'addle'='TWADDLE'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for twaddle that I've seen before include "Rubbish" , "Trivial speech or writing" , "Senseless talk" , "Stuff and nonsense" , "bunk" .)
