Simple example of art degree a great many left incomplete (6)
I believe the answer is:
doodle
'simple example of art' is the definition.
I can't judge whether this defines the answer.
'degree a great many left incomplete' is the wordplay.
'degree' becomes 'd' (abbreviation for the degree in measuring angles).
'a great many' becomes 'oodles' (oodles informally means a lot of something).
'left incomplete' means to remove the last letter.
'oodles' with its last letter removed is 'oodle'.
'd'+'oodle'='DOODLE'
Can you help me to learn more?
(Other definitions for doodle that I've seen before include "Draw aimlessly" , "Aimless drawing" , "Absent-minded drawing" , "Casual drawing" , "Poem by Byron; king of Sicily" .)
