Business community welcomes reliable merger (13)
I believe the answer is:
consolidation
'merger' is the definition.
(thesaurus)
'business community welcomes reliable' is the wordplay.
'business community' becomes 'conation' (I can't explain this - if you can you should believe this answer much more).
'welcomes' is an insertion indicator (in sense of 'invites in').
'reliable' becomes 'solid' (I've seen this in another clue).
'conation' enclosing 'solid' is 'CONSOLIDATION'.
Can you help me to learn more?
(Other definitions for consolidation that I've seen before include "Act of combining into one" , "reinforcement" .)
