Expressed regret in article composed about record (10)
I believe the answer is:
apologised
'expressed regret' is the definition.
(I've seen this before)
'article composed about record' is the wordplay.
'article' becomes 'a' (indefinite article).
'composed' becomes 'poised' ('poised' can be similar in meaning to 'composed'**).
'about' indicates putting letters inside.
'record' becomes 'log' (logging is a kind of recording).
'poised' enclosing 'log' is 'pologised'.
'a'+'pologised'='APOLOGISED'
'in' is the link.
(Other definitions for apologised that I've seen before include "Expressed regret for what one has done" , "admitted faults" , "Was sorry" .)
