Lord socially acceptable in disorganised clan (5)
I believe the answer is:
lucan
'lord socially' is the definition.
The definition suggests a singular noun which matches the answer.
'acceptable in disorganised clan' is the wordplay.
'acceptable' becomes 'u' ((Film classification)).
'in' indicates putting letters inside.
'disorganised' is an anagram indicator.
'clan' with letters rearranged gives 'lcan'.
'u' inserted into 'lcan' is 'LUCAN'.
Can you help me to learn more?
(Other definitions for lucan that I've seen before include "found in one of the gospels?" , "Notorious fugitive peer" , "Roman poet - vanishing lord" , "Lord who famously went missing" , "Roman poet; a missing Lord" .)
