Delicate thing that might be struck? (5)
I believe the answer is:
light
'delicate' is the definition.
(similar in meaning)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for light that I've seen before include "Settle" , "Illumination - not serious!" , "Match - agile - easily digested" , "Airy; not heavy" , "Weightless; lamp" .)
