Skill shown, I start to weave line (8)
I believe the answer is:
artistry
'skill' is the definition.
(thesaurus)
'i start to weave line' is the wordplay.
'to weave' indicates an anagram.
'line' becomes 'ry' (abbreviation for railway).
'i'+'start'='istart'
'istart' is an anagram of 'artist'.
'artist'+'ry'='ARTISTRY'
'shown' acts as a link.
I am not very happy about this link. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for artistry that I've seen before include "Creative skill learned by study and practice" , "The skill to create works of art" , "Creative workmanship" , "Skilled workmanship" , "great skill" .)
