Dan's prepared to become like George
I believe the answer is:
sand
'like george' is the definition.
'sand' can be an answer for 'george' (I've seen this before). I'm unsure of the 'like' bit.
'dan's prepared' is the wordplay.
'prepared' indicates anagramming the letters.
'dans' with letters rearranged gives 'SAND'.
'to become' is the link.
Can you help me to learn more?
(Other definitions for sand that I've seen before include "Shore grains" , "Parts of beach" , "Desert material" , "Smooth down (surface)" , "Shore grain" .)
