Solution requiring large and little woman? (6)
I believe the answer is:
bigamy
'solution' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'large and little woman?' is the wordplay.
'large' becomes 'big' (synonyms).
'and' means one lot of letters go next to another.
'little woman?' becomes 'Amy' (character from the novel Little Women).
'big'+'amy'='BIGAMY'
'requiring' acts as a link.
Can you help me to learn more?
(Other definitions for bigamy that I've seen before include "Marrying one person while married to another" , "overmatiness" , "Having more than one spouse, illegally" , "Crime of double marriage" , "Crime involving two better halves!" .)
