Point in old article showing hidden motivation? (6)
I believe the answer is:
agenda
'hidden motivation?' is the definition.
(as in a hidden agenda)
'point in old article' is the wordplay.
'point' becomes 'n' (N is an example).
'in' means one lot of letters goes inside another.
'old' becomes 'aged' (similar in meaning).
'article' becomes 'a' (the indefinite article in English).
'n' inserted within 'aged' is 'agend'.
'agend'+'a'='AGENDA'
'showing' acts as a link.
(Other definitions for agenda that I've seen before include "List of items to be done" , "matters for discussion" , "Business to be transacted" , "Individual objective(s)" , "List of items to be dealt with" .)
