A report about damaged tin foil (10)

I believe the answer is:
antithesis
'foil' is the definition.
(thesaurus)
'a report about damaged tin' is the wordplay.
'report' becomes 'thesis' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'about' means one lot of letters go next to another.
'damaged' indicates an anagram.
'tin' with letters rearranged gives 'nti'.
'thesis' put after 'nti' is 'ntithesis'.
'a'+'ntithesis'='ANTITHESIS'
Can you help me to learn more?
(Other definitions for antithesis that I've seen before include "I oppose the suggestion" , "Direct opposite" , "Contrast between two things" , "Opposite; contrasting idea" , "Reverse" .)
