Eggheads about to send for a recluse (7)
I believe the answer is:
eremite
'for a recluse' is the definition.
(I've seen this in another clue)
'eggheads about to send' is the wordplay.
'eggheads' becomes 'ee' (I can't justify this - if you can you should give a lot more credence to this answer).
'about' is an insertion indicator.
'to send' becomes 'remit' (I've seen this in another clue).
'ee' going around 'remit' is 'EREMITE'.
Can you help me to learn more?
(Other definitions for eremite that I've seen before include "ascetic" , "desert father" , "Christian living in severe circumstances" , "Religious person" , "Solitary" .)
