Drug problem involving king's personal servant? (7)
I believe the answer is:
equerry
'personal servant?' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe you can see a link between them that I don't see?
'drug problem involving king's' is the wordplay.
'drug' becomes 'e' (e is another name for ecstasy).
'problem' becomes 'query' (I can't explain this - if you can you should believe this answer much more).
'involving' means one lot of letters goes inside another.
'king' becomes 'r' (r is abbreviation for rex).
'query' placed around 'r' is 'querry'.
'e'+'querry'='EQUERRY'
Can you help me to learn more?
(Other definitions for equerry that I've seen before include "Attendant at palace" , "Officer attending a royal family member" , "Attendant in royal household" , "Personal attendant of a member of the royal family" , "Sovereign's officer" .)
