Dog trained for keeping at home? Not this one (5)
I believe the answer is:
dingo
'home? not this one' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'dog trained for keeping at' is the wordplay.
'trained' indicates anagramming the letters (to train can mean to grow something into a shape).
'for keeping' means one lot of letters goes inside another.
'at' becomes 'in'.
'dog' with letters rearranged gives 'dgo'.
'dgo' enclosing 'in' is 'DINGO'.
Can you help me to learn more?
(Other definitions for dingo that I've seen before include "Wild Australian dog" , "Wild thing" , "Aus. wild dog" , "Scavenger" , "Aussie wild dog" .)
