Conduct my own to source of metal (8)
I believe the answer is:
leadmine
'conduct my own to source of metal' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.
'conduct my own to source of metal' is the wordplay.
'conduct' becomes 'lead' (conduct can mean to lead someone somewhere).
'my' becomes 'ine' (I can't explain this - if you can you should give a lot more credence to this answer).
'own' means one lot of letters goes inside another.
'to source of' says to take the initial letters.
The first letter of 'metal' is 'm'.
'lead'+'ine'='leadine'
'leadine' enclosing 'm' is 'LEADMINE'.
Can you help me to learn more?
