Amateur correctly grips both sides of coil in device providing illumination (3,5)
I believe the answer is:
arc light
'device providing illumination' is the definition.
I can't tell whether this defines the answer.
'amateur correctly grips both sides of coil' is the wordplay.
'amateur' becomes 'a'.
'correctly' becomes 'right' (synonyms).
'grips' indicates putting letters inside.
'both sides of' suggests removing the centre (only the letters on the sides remain).
'coil' with its middle removed is 'cl'.
'right' enclosing 'cl' is 'rclight'.
'a'+'rclight'='ARC-LIGHT'
'in' is the link.
Can you help me to learn more?
(Other definitions for arc light that I've seen before include "Lamp using electric discharge" , "Shiner" , "Electric source of light" , "It will help people see" , "Bright source" .)
