A prickly character chases Mike regarding order (7)
I believe the answer is:
masonic
'a prickly' is the definition.
I can't judge whether this definition defines the answer.
'character chases mike regarding order' is the wordplay.
'character' becomes 'a'.
'chases' is a charade indicator (letters next to each other).
'mike' becomes 'm' (phonetic alphabet: alpha, bravo, charlie etc.).
'regarding order' becomes 'sonic' (I am not sure about this - if you are sure you should believe this answer much more).
'a' after 'm' is 'ma'.
'ma'+'sonic'='MASONIC'
Can you help me to learn more?
(Other definitions for masonic that I've seen before include "of lodgers?" , "Ma's coin (anag.)" , "Branch of secret male society" , "Like some lodges" , "Local branch of secret society" .)
