English monarch supporting dying cause (8)
I believe the answer is:
engender
'english monarch supporting dying cause' is the definition.
I can't tell whether this definition defines the answer.
'english monarch supporting dying cause' is the wordplay.
'english' becomes 'eng' (abbreviation).
'monarch' becomes 'ER' (abbreviation for Elizabeth Regina, British Queen).
'supporting' is a charade indicator (letters next to each other) (in a down clue, some letters go below others).
'dying cause' becomes 'end' (end is a kind of cause. I am not sure about the 'dying' bit.).
'er' after 'end' is 'ender'.
'eng'+'ender'='ENGENDER'
Can you help me to learn more?
(Other definitions for engender that I've seen before include "Produce or cause, emotions say" , "Generate - green den (anag)" , "Bring forth" , "Give rise to, cause" , "Precipitate" .)
