Caught light in strong grip (5)
I believe the answer is:
clamp
'strong grip' is the definition.
'clamp' can be an answer for 'grip' (I've seen this in another clue). I'm unsure of the 'strong' bit.
'caught light' is the wordplay.
'caught' becomes 'c' (cricket abbreviation).
'light' becomes 'lamp' (lamp is a kind of light).
'c'+'lamp'='CLAMP'
'in' is the link.
Can you help me to learn more?
(Other definitions for clamp that I've seen before include "pile of turf" , "squeeze" , "Firmly press" , "Device for holding things tightly" , "Heap of potatoes" .)
