Home visitor in fight to break up domestic argument? (5,7)
I believe the answer is:
house sparrow
'break up domestic argument?' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'home visitor in fight' is the wordplay.
'home' becomes 'house' (I've seen this before).
'visitor in fight' becomes 'sparrow' (I can't justify this - if you can you should believe this answer much more).
'house'+'sparrow'='HOUSE SPARROW'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for house sparrow that I've seen before include "one chirpy?" , "Winger" , "Flier" .)
