With passion, a creation can be a cracker! (8)
I believe the answer is:
firework
'a cracker' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'with passion a creation' is the wordplay.
'with' means one lot of letters go next to another.
'passion' becomes 'fire' (fire is a kind of passion).
'a creation' becomes 'work' (work is a kind of creation).
'fire'+'work' is 'FIREWORK'.
'can be' acts as a link.
Can you help me to learn more?
(Other definitions for firework that I've seen before include "rocket" , "fountain, say" , "Pyrotechnic device" , "Banger, for example" , "Colourful incendiary device used for entertainment" .)
