Sprang up after the end of a shower (4)
I believe the answer is:
rose
'sprang up' is the definition.
(rise can mean to spring up)
'after the end of a shower' is the wordplay.
'the end of' indicates one should take the final letters.
'a shower' becomes 'ose' (I am not sure about this - if you are sure you should believe this answer much more).
The last letter of 'after' is 'r'.
'r'+'ose'='ROSE'
Can you help me to learn more?
(Other definitions for rose that I've seen before include "' a . . . ./By any other name would smell as sweet' (Shakespeare)" , "Herb - girl's name(s)" , "Old song 'The last . . . of summer'" , "Perforated nozzle" , "Garden flower" .)
