Select rodents that feature terminal of battery (9)
I believe the answer is:
electrode
'terminal of battery' is the definition.
'electrode' can be an answer for 'terminal'. I am not sure about the 'of battery' bit.
'select rodents that feature' is the wordplay.
'that feature' says the answer is hidden in the clue (I've seen 'featuring' mean this).
'ELECTRODE' is hidden in the letters of 'select rodents'.
Can you help me to learn more?
(Other definitions for electrode that I've seen before include "Conductor making contact in a circuit" , "Conducting contact" , "Connecting conductor" , "Conductor by which current enters" , "Conducting point by which electric current enters or leaves" .)
