Rod will make a change (6)
I believe the answer is:
switch
This clue is a quadruple definition!!
'rod' is the first definition.
(thesaurus)
'will' is the second definition.
The answer and definition can be both to do with ownership as well as being verbs in their base form.
Perhaps you can see an association between them that I don't see?
'make' is the third definition.
(thesaurus)
'a change' is the fourth definition.
(switch is a kind of change)
Can you help me to learn more?
(Other definitions for switch that I've seen before include "Circuit-breaker" , "Change; hair-piece" , "Change or cane" , "Exchange positions for flexible rod or whip" , "On/off device" .)
