Institute a bit less disorganised when set beside hospital (9)
I believe the answer is:
establish
'institute' is the definition.
(synonyms)
'a bit less disorganised when set beside hospital' is the wordplay.
'disorganised' is an anagram indicator.
'when set beside' means one lot of letters go next to another.
'hospital' becomes 'h' (abbreviation for hospital on maps).
'a'+'bit'+'less'='abitless'
'abitless' is an anagram of 'establis'.
'establis'+'h'='ESTABLISH'
(Other definitions for establish that I've seen before include "Found - institute" , "Show to be true in his stable" , "Set up or found" , "Found or authenticate" , "Verify" .)
