Another card please, from spades in dummy (5)
I believe the answer is:
twist
'another card please' is the definition.
I can't judge whether this defines the answer.
'spades in dummy' is the wordplay.
'spades' becomes 's' (abbreviation in card games).
'in' means one lot of letters goes inside another.
'dummy' becomes 'twit' (I am not sure about this - if you are sure you should believe this answer much more).
's' going within 'twit' is 'TWIST'.
'from' acts as a link.
Can you help me to learn more?
(Other definitions for twist that I've seen before include "Unexpected event" , "Rotate -- dance" , "Wring" , "One who asked for more" , "Embellishment to plot" .)
