'Switched on' energy? (5)
I believe the answer is:
power
This might be a double definition.
'switched' is the first definition.
The answer and definition are different parts of speech. However, past participle verbs and adjectives can occasionally define each other.
'energy?' is the second definition.
(I know that power is a type of energy)
'on' acts as a link.
Can you help me to learn more?
(Other definitions for power that I've seen before include "index" , "Physical force, ability" , "military force" , "Military potential" , "- - of attorney" .)
