Flower makes bully lose his footing (7)
I believe the answer is:
cowslip
'flower' is the definition.
(thesaurus)
'bully lose his footing' is the wordplay.
I cannot really understand how this works, but
'bully' could be 'cow' (I've seen this before) and 'cow' is present 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 clue (or it may be nonsense).
'makes' acts as a link.
Can you help me to learn more?
(Other definitions for cowslip that I've seen before include "Yellow flower for unsteady bovine?" , "bloomers cover this" , "Type of primrose" , "Flower related to primrose" , "Wild yellow primula" .)
