Sew up ruptured uterus (6)
I believe the answer is:
suture
'sew up' is the definition.
Both the definition and answer are verbs in their base form.
Perhaps there's a link between them I don't understand?
'ruptured uterus' is the wordplay.
'ruptured' is an anagram indicator.
'uterus' with letters rearranged gives 'SUTURE'.
Can you help me to learn more?
(Other definitions for suture that I've seen before include "Stitch holding together the edges of a wound" , "Medical stitching" , "Stitches (in wound)" , "Stitch for 31ac" , "Surgical stitching" .)
