Written by some arty pedants? (5)
I believe the answer is:
typed
'written' is the definition.
(typing is a kind of writing)
'some arty pedants?' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'TYPED' can be found hidden inside 'arty pedants'.
'by' is the link.
(Other definitions for typed that I've seen before include "Written on a keyboard" , "neatly presented?" .)
