Memos involving damaged stone (5)
I believe the answer is:
notes
'memos' is the definition.
(I've seen this before)
'damaged stone' is the wordplay.
'damaged' indicates anagramming the letters.
'stone' is an anagram of 'NOTES'.
'involving' acts as a link.
(Other definitions for notes that I've seen before include "Marks on a stave" , "Lines" , "Paper money" , "Memoranda" , "Stone with jottings" .)
