Love one to work for their share (9)
I believe the answer is:
adoration
'love' is the definition.
(I've seen this before)
'their share' is the wordplay.
'their' becomes 'ado' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'share' becomes 'ration' (ration is a kind of share).
'ado'+'ration'='ADORATION'
'one to work for' is the link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for adoration that I've seen before include "What star gets from fans" , "high regard" , "Feeling of profound love" , "Honour" , "Not a radio (anag.)" .)
