Father requiring pair of pears, oddly (4)
I believe the answer is:
papa
'father' is the definition.
(papa is a kind of father)
'pair of pears oddly' is the wordplay.
'pair of' says to double the letters (I've seen 'pair' mean this).
'pears oddly' becomes 'pa' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'pa' duplicated is 'PAPA'.
'requiring' acts as a link.
Can you help me to learn more?
(Other definitions for papa that I've seen before include "Father; P (radio comms.)" , "Father; letter P" , "Dad" , "Comms code for 'P'" , "The old man" .)
