Choose right coin, fashioned using current (10)
I believe the answer is:
electronic
'current' is the definition.
Although both the answer and definition are adjectives, I can't see how one could define the other.
'choose right coin fashioned' is the wordplay.
'choose' becomes 'elect' (electing is a kind of choosing).
'right' becomes 'r' (abbreviation).
'fashioned' is an anagram indicator.
'coin' is an anagram of 'onic'.
'elect'+'r'+'onic'='ELECTRONIC'
'using' acts as a link.
Can you help me to learn more?
(Other definitions for electronic that I've seen before include "Like a PC" , "Like microcircuitry" , "using a computer?" , "Using microchips, transistors, etc" , "Relating to micro-circuitry" .)
