Perhaps old Dutch gold rings right for dabbler (7)
I believe the answer is:
amateur
'dabbler' is the definition.
(I've seen this in another clue)
'perhaps old dutch gold rings right' is the wordplay.
'perhaps old dutch' becomes 'mate' (I can't explain this - if you can you should give a lot more credence to this answer).
'gold' becomes 'Au' (Au is the chemical symbol for gold).
'rings' means one lot of letters goes inside another (some letters are ringed or contained by others).
'right' becomes 'r' (common abbreviation).
'mate' going into 'au' is 'amateu'.
'amateu'+'r'='AMATEUR'
'for' is the link.
Can you help me to learn more?
(Other definitions for amateur that I've seen before include "Tum area (anag.)" , "Ham" , "Of sportsman, not professional" , "Inexpert" , "Engaged in as a pastime" .)
