Treadle corrected and connected (7)
I believe the answer is:
related
'connected' is the definition.
(relating is a kind of connecting)
'treadle corrected' is the wordplay.
'corrected' indicates an anagram.
'treadle' is an anagram of 'RELATED'.
'and' is the link.
(Other definitions for related that I've seen before include "Akin, associated" , "Narrated; connected" , "Told; linked" , "Having family links" , "Told in detail, being connected" .)
