Suggest some sterling support? (8)
I believe the answer is:
propound
'suggest' is the definition.
(propounding is a kind of suggesting)
'some sterling support?' is the wordplay.
'some' becomes 'pro' (I can't justify this - if you can you should give a lot more credence to this answer).
'sterling' becomes 'pound'.
'support?' is a charade indicator (letters next to each other) (in a down clue, some letters hold others up).
'pro'+'pound'='PROPOUND'
Can you help me to learn more?
(Other definitions for propound that I've seen before include "Advance" , "Offer for consideration" , "Put forward an idea for consideration" , "Make a submission" , "move?" .)
