Stick out for last half of Magic Roundabout character (8)
I believe the answer is:
protrude
'stick out' is the definition.
(I know that stick out can be written as protrude)
'last half of magic roundabout character' is the wordplay.
'last' becomes 'pro' (I can't justify this - if you can you should give a lot more credence to this answer).
'half of' means to take half the letters.
'magic roundabout character' becomes 'Ermintrude' (character from The Magic Roundabout).
'ermintrude' cut in half is 'trude'.
'pro'+'trude'='PROTRUDE'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for protrude that I've seen before include "Thrust forward" , "Point out" , "Stick out, project from a surface" , "Get through" , "Stick outwards" .)
