Not influenced by menu I'm arranging (6)
I believe the answer is:
immune
'not influenced' is the definition.
The answer and definition are different parts of speech. However, adjectives and past participle verbs occasionally mean the same thing.
'by menu i'm arranging' is the wordplay.
'by' says to put letters next to each other.
'arranging' is an anagram indicator.
'menu' next to 'im' is 'menuim'.
'menuim' anagrammed gives 'IMMUNE'.
Can you help me to learn more?
(Other definitions for immune that I've seen before include "Not susceptible to, say after inoculation" , "Not liable to, protected from" , "Inoculated or exempt" , "Protected - unaffected" , "Secure against, infection say" .)
