Most recent article in French trial (6)
I believe the answer is:
latest
'most recent' is the definition.
('late' can be similar in meaning to 'recent')
'article in french trial' is the wordplay.
'article in french' becomes 'la' ('the', the definite article in French).
'trial' becomes 'test' (synonyms).
'la'+'test'='LATEST'
(Other definitions for latest that I've seen before include "News update" , "Current" , "Most up to the minute" , "Most recent, hot off the press" , "State-of-the-art" .)
