Children’s author to pass on marginal artwork (6)
I believe the answer is:
sendak
'marginal artwork' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.
'children's author to pass on' is the wordplay.
'children's author' becomes 'ak' (I can't justify this - if you can you should believe this answer much more).
'to' means one lot of letters go next to another (I've seen this in other clues).
'pass on' becomes 'send' (I've seen this in another clue).
'ak' put after 'send' is 'SENDAK'.
Can you help me to learn more?
(Another definition for sendak that I've seen is " Maurice -- (Where the Wild Things Are)".)
