A woman to cheat at some risk (5)
I believe the answer is:
doris
'a woman' is the definition.
(I've seen this before)
'cheat at some risk' is the wordplay.
'cheat' becomes 'do'.
'at' means one lot of letters go next to another.
'some risk' becomes 'ris' (I can't justify this - if you can you should give a lot more credence to this answer).
'do'+'ris'='DORIS'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for doris that I've seen before include "In Greek myth, wife of sea-god Nereus" , "Girl" , "Woman's name" , "Female name" , "Woman" .)
