Scrapping alibi, not worried about nothing (9)
I believe the answer is:
abolition
'scrapping alibi not worried about nothing' is the definition.
I can't judge whether this definition defines the answer.
'alibi not worried about nothing' is the wordplay.
'worried' indicates an anagram.
'about' means one lot of letters goes inside another.
'nothing' becomes 'O' (looks like zero - 0).
'alibi'+'not'='alibinot'
'alibinot' with letters rearranged gives 'abolitin'.
'abolitin' going around 'o' is 'ABOLITION'.
Can you help me to learn more?
(Other definitions for abolition that I've seen before include "Complete ending (of something)" , "Act of putting an end to something" , "Removal of" , "Wilberforce achieved it" , "Eradication" .)
