Local official has almost all dreamland confused
I believe the answer is:
alderman
'local official' is the definition.
'alderman' can be an answer for 'official' (I've seen this before). I'm unsure of the 'local' bit.
'almost all dreamland confused' is the wordplay.
'almost all' means to remove the last letter.
'confused' indicates an anagram.
'dreamland' with its final letter removed is 'dreamlan'.
'dreamlan' is an anagram of 'ALDERMAN'.
'has' acts as a link.
Can you help me to learn more?
(Other definitions for alderman that I've seen before include "Civic officer" , "Old municipal official" , "Member of a local legislative body" , "Former civic dignitary" , "Member of English county council" .)
