Drunken orderly entertaining northern lecturer in the city (11)
I believe the answer is:
londonderry
'the city' is the definition.
Both the definition and answer are singular nouns.
Maybe there's a link between them I don't understand?
'drunken orderly entertaining northern lecturer' is the wordplay.
'drunken' indicates an anagram.
'entertaining' is an insertion indicator (inviting in, as for dinner).
'northern' becomes 'n' (abbreviation e.g. N. Ireland).
'lecturer' becomes 'don' (don can mean an academic).
'orderly' is an anagram of 'loderry'.
'n'+'don'='ndon'
'loderry' placed around 'ndon' is 'LONDONDERRY'.
'in' acts as a link.
Can you help me to learn more?
(Another definition for londonderry that I've seen is " One name of Northern Ireland city".)
