Set up mine with revolutionary daughter (7)
I believe the answer is:
pitched
'set up' is the definition.
Both the definition and answer are adjectives. Maybe they are linked in a way I don't understand?
'mine with revolutionary daughter' is the wordplay.
'mine' becomes 'pit' (down the pit).
'with' means one lot of letters go next to another.
'revolutionary' becomes 'Che' (Che Guevara the Marxist revolutionary).
'daughter' becomes 'd' (genealogical abbreviation).
'pit'+'che'+'d'='PITCHED'
Can you help me to learn more?
(Other definitions for pitched that I've seen before include "cast" , "Set on a particular musical note" , "Threw" .)
