To me, a piece of writing has value (5)
I believe the answer is:
merit
'value' is the definition.
(I've seen this in another clue)
'to me a piece of writing' is the wordplay.
'a piece of writing' becomes 'rit' (I can't explain this - if you can you should believe this answer much more).
'me'+'rit'='MERIT'
'has' acts as a link.
Can you help me to learn more?
(Other definitions for merit that I've seen before include "Earn" , "of a high order?" , "Value" , "Have a right" , "credit" .)
