Matter-of-fact articles rewritten about first person (9)
I believe the answer is:
realistic
'matter-of-fact' is the definition.
(thesaurus)
'articles rewritten about first person' is the wordplay.
'rewritten' indicates an anagram.
'about' means one lot of letters goes inside another.
'first person' becomes 'I' (first-person pronoun).
'articles' with letters rearranged gives 'realistc'.
'realistc' placed around 'i' is 'REALISTIC'.
(Other definitions for realistic that I've seen before include "believable" , "Practicable" , "It is clear, being practical and sensible" , "Down-to-earth" , "Without illusions, dealing in facts" .)
