Relations with general ruler (4)
I believe the answer is:
king
'ruler' is the definition.
(king is a kind of ruler)
'relations with general' is the wordplay.
'relations' becomes 'kg' (I can't justify this - if you can you should believe this answer much more).
'with' indicates putting letters inside.
'general' becomes 'in general' (similar in meaning).
'kg' placed around 'in' is 'KING'.
Can you help me to learn more?
(Other definitions for king that I've seen before include "Man with a crown" , "Chesspiece which mustn't be lost" , "Male ruler" , "Play set in medieval Britain" , "Playing-card" .)
