Female organs found in some resolute rioters (5)
I believe the answer is:
uteri
'female organs' is the definition.
'uteri' can be an answer for 'organs' (plural of uterus). I'm not sure about the 'female' bit.
'in some resolute rioters' is the wordplay.
'in' indicates a hidden word.
'UTERI' can be found hidden inside 'some resolute rioters'.
'found' acts as a link.
Can you help me to learn more?
(Other definitions for uteri that I've seen before include "Wombs" , "organs, in hospital patients" , "baby carriers" , "Organs for girls" , "Organs reproducing" .)
