50% fake goes into plant probably (6)
I believe the answer is:
likely
'probably' is the definition.
(synonyms)
'50 fake goes into plant' is the wordplay.
'50' indicates taking half.
'goes into' indicates putting letters inside.
'plant' becomes 'lily' (I am not sure about this - if you are sure you should believe this answer much more).
'fake' cut in half is 'ke'.
'ke' going into 'lily' is 'LIKELY'.
Can you help me to learn more?
(Other definitions for likely that I've seen before include "Such as well might happen" , "Promising, probably" , "Ilkley (anag.)" , "Quite possible" , "Promising; probable" .)
