Brought missing top and scored (6)
I believe the answer is:
etched
'scored' is the definition.
The definition and answer can be both to do with creating things as well as being past participle verbs.
Perhaps they are linked in a way I don't understand?
'brought missing top' is the wordplay.
'brought' becomes 'fetched' ('fetch' can be a synonym of 'bring').
'missing top' means to remove the first letter.
'fetched' with its first letter taken away is 'ETCHED'.
'and' is the link.
Can you help me to learn more?
(Other definitions for etched that I've seen before include "Carved on metal with acid" , "Incised" , "Engraved, eg, by acid" , "made some kind of score" , "Cut or impressed into a surface" .)
