Be a bit floppy (3)
I believe the answer is:
lop
'floppy' is the definition.
(thesaurus)
'be a bit' is the wordplay.
I cannot really understand how this works, but
'bit' could be 'o' (resembles 0, a binary digit or bit) and 'o' is present in the answer.
The remaining letters 'lp' 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).
Can you help me to learn more?
(Other definitions for lop that I've seen before include "Prune, cut the top off" , "Remove branches from a tree" , "Cut (e.g. branch off)" , "Cut away branches or twigs" , "Chop (off)" .)
