Dickens will accept article for Ruth's husband (4)
I believe the answer is:
boaz
'ruth's husband' is the definition.
The definition suggests a singular noun which matches the answer.
'dickens will accept article' is the wordplay.
'dickens' becomes 'boz' (I've seen this in other clues).
'will accept' means one lot of letters goes inside another.
'article' becomes 'a' (indefinite article).
'boz' going around 'a' is 'BOAZ'.
'for' is the link.
Can you help me to learn more?
(Other definitions for boaz that I've seen before include "Ruth's husband (OT)" , "Ruth's husband (Old Testament)" .)
