Stood up for a lady (4)
I believe the answer is:
rose
I believe this is a double definition.
'stood up' is the first definition.
(I've seen this before)
'a lady' is the second definition.
'for' is the link.
(Other definitions for rose that I've seen before include "''That which we call a ..., by any other name would smell as sweet'' (Romeo and Juliet)" , "Prickly plant with bright flowers" , "Floral emblem of England" , "Flower - ascended" , "Herb - girl's name(s)" .)
