Article obtainable from a dealer (6)
I believe the answer is:
leader
'article' is the definition.
(thesaurus)
'from a dealer' is the wordplay.
'from' is an anagram indicator (from the letters).
'dealer' is an anagram of 'LEADER'.
'obtainable' is the link.
I am not very happy about this link. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for leader that I've seen before include "source of inspiration" , "Superior" , "Head of an orchestra" , "Editor's article" , "One inspires or guides others" .)
