Choose lyric about Queen for conductor (9)
I believe the answer is:
electrode
'for conductor' is the definition.
(electrode is a kind of conductor)
'choose lyric about queen' is the wordplay.
I cannot really understand how this works, but
'choose' could be 'elect' (electing is a kind of choosing) and 'elect' is found in the answer.
'lyric' could be 'ode' (ode is a kind of lyric) and 'ode' is found within the answer.
'queen' could be 'r' (abbreviation for regina, e.g. in ER ) and 'r' is present in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for electrode that I've seen before include "Connecting conductor" , "Conductor making contact in a circuit" , "Conductor for electricity as it enters or leaves" , "Conductor by which current enters" , "Conducting contact" .)
