More precisely, repeatedly runs across two articles (6)
I believe the answer is:
rather
'more precisely' is the definition.
('or rather' means 'or more precisely')
'repeatedly runs across two articles' is the wordplay.
'two articles' can mean two replacements for 'article'.
'repeatedly' says to double the letters.
'runs' becomes 'r' (cricket abbreviation).
'across' is an insertion indicator.
'article' becomes 'a' (the indefinite article in English).
'article' becomes 'the' (the definite article in English).
'r' duplicated is 'rr'.
'a'+'the'='athe'
'rr' placed around 'athe' is 'RATHER'.
(Other definitions for rather that I've seen before include "To a limited degree" , "A bit" , "On the contrary; more precisely" , "Quite, sort of" , "somewhat > sooner? > Quite" .)
