Sensational duck, wicket given after loud cry (6)
I believe the answer is:
yellow
'sensational' is the definition.
('yellow' can be similar in meaning to 'sensational')
'duck wicket given after loud cry' is the wordplay.
'duck' becomes 'o'.
'wicket' becomes 'w'.
'given after' means one lot of letters go next to another.
'loud cry' becomes 'yell' (I've seen this before**).
'o'+'w'='ow'
'ow' after 'yell' is 'YELLOW'.
(Other definitions for yellow that I've seen before include "Colour of egg yolk and cowardice" , "Lemon shade" , "Colour of the fever flag" , "Daffodil colour" , "Colour of cowardice, custard" .)
