Bobby, Apollonia and Mark Brown initially hula-hoop over grass (6)
I believe the answer is:
bamboo
'grass' is the definition.
(I've seen this before)
'bobby apollonia and mark brown initially hula-hoop over' is the wordplay.
I cannot really understand how this works, but
'mark' could be 'm' and 'm' is located in the answer.
'hoop' could be 'o' and 'o' is located in the answer.
'over' could be 'o' (cricket abbreviation) and 'o' is present in the answer.
The remaining letters 'bab' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for bamboo that I've seen before include "Tropical grass/wood" , "Woody tropical grass with a hollow stem" , "Type of cane" , "Giant woody grass" , "Tropical grass with strong hollow stems" .)
