Flowers or grass being munched may dangle from them (8)
I believe the answer is:
'flowers' is the definition.
The definition and answer can be both plants as well as being plural nouns.
Maybe they are linked in a way I don't understand?
'grass being munched may dangle from them' is the wordplay.
I cannot quite see how this works, but
'being' could be 'slip' (slip is a kind of being) and 'slip' is found in the answer.
'from' could be 'o' (I've seen this in other clues) and 'o' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
'or' acts as a link.
Can you help me to learn more?
(Other definitions for cowslips that I've seen before include "pretty yellow flowers for unsteady bovine" , "Wild yellow flowers for unsteady bovines" .)
