Aim revealed by creature with venom and anger (6)
I believe the answer is:
aspire
'aim' is the definition.
(synonyms)
'creature with venom and anger' is the wordplay.
I cannot really understand how this works, but
'anger' could be 'ire' (ire is intense rage) and 'ire' is located in the answer.
The remaining letters 'asp' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'revealed by' is the link.
Can you help me to learn more?
(Other definitions for aspire that I've seen before include "rise to a great height" , "Wish to rise (to)" , "Earnestly desire (to achieve something)" , "Have ambition (to achieve something)" , "Set your sights on" .)
