Could it make the parker see the light? (5)
I believe the answer is:
clamp
'could it make the parker' is the definition.
I can't judge whether this definition defines the answer.
'see the light?' is the wordplay.
'see' becomes 'c' (the word for the letter, according to Chambers).
'the light?' becomes 'lamp' (lamp is a kind of light**).
'c'+'lamp'='CLAMP'
Can you help me to learn more?
(Other definitions for clamp that I've seen before include "Strong fastener" , "Of car, render immobile for parking offence" , "Secure - store for potatoes" , "squeeze" , "Heap of potatoes" .)
