Is it growing to be a bit of a beast? (7)
I believe the answer is:
cowslip
'is it growing to be a bit' is the definition.
I can't judge whether this defines the answer.
'a beast?' is the wordplay.
I cannot quite see how this works, but
'beast?' could be 'cow' (cow is a kind of beast) and 'cow' is found in the answer.
The remaining letters 'slip' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'of' is the link.
Can you help me to learn more?
(Other definitions for cowslip that I've seen before include "Type of primrose" , "bloomers cover this" , "Wild spring flower" , "Pretty little wild flower for unsteady bovine" , "Yellow flower for unsteady bovine?" .)
