Wonderful game is played (4)
I believe the answer is:
mega
'wonderful' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.
'game is played' is the wordplay.
'is played' indicates anagramming the letters (letters playing around).
'game' with letters rearranged gives 'MEGA'.
Can you help me to learn more?
(Other definitions for mega that I've seen before include "Informally great or large" , "Very large (prefix)" , "As brilliant" , "wicked" , "Fantastic!" .)
