Claret is unusual material for press features (8)
I believe the answer is:
articles
'material for press features' is the definition.
I can't tell whether this definition defines the answer.
'claret is unusual' is the wordplay.
'unusual' is an anagram indicator.
'claret'+'is'='claretis'
'claretis' is an anagram of 'ARTICLES'.
Can you help me to learn more?
(Other definitions for articles that I've seen before include "Recitals about particular things" , "Recitals (anag.)" , "Recitals about newspaper features" , "Legal apprenticeship" , "Recitals for newspaper pieces" .)
