Delete parts of score composed around noon (6)
I believe the answer is:
censor
'delete parts' is the definition.
'censor' can be an answer for 'delete' (thesaurus). I am not sure about the 'parts' bit.
'score composed around noon' is the wordplay.
'composed' is an anagram indicator.
'around' indicates putting letters inside.
'noon' becomes 'n' (abbreviation).
'score' is an anagram of 'cesor'.
'cesor' going around 'n' is 'CENSOR'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for censor that I've seen before include "Suppress anything considered obscene or politically unacceptable" , "State official who vets books etc for crones" , "Blue-pencilling official" , "Blue-pencil official" , "Wield a blue pencil" .)
