Connected ideas a Scot worked out (10)
I believe the answer is:
associated
'connected' is the definition.
('associated' can be a synonym of 'connected')
'ideas a scot worked out' is the wordplay.
'worked out' indicates anagramming the letters.
'ideas'+'a'+'scot'='ideasascot'
'ideasascot' is an anagram of 'ASSOCIATED'.
(Other definitions for associated that I've seen before include "Linked" , "Went about with" , "Connected (with)" , "Made a logical or causal connection" , "in a group, perhaps" .)
