Called to account, a king showered around midnight (9)
I believe the answer is:
arraigned
'called to account' is the definition.
I can't judge whether this defines the answer.
'a king showered around midnight' is the wordplay.
'king' becomes 'R' (abbreviation for rex, king in Latin).
'showered' becomes 'rained' (showers of rain).
'around' indicates putting letters inside.
'midnight' becomes 'g' (the middle letter in 'night').
'rained' enclosing 'g' is 'raigned'.
'a'+'r'+'raigned'='ARRAIGNED'
Can you help me to learn more?
(Other definitions for arraigned that I've seen before include "Indicted" , "accused" , "Called before a court to answer an indictment" .)
