Dog leashed to protect property close to beach (6,5)
I believe the answer is:
basset hound
'dog' is the definition.
(basset hound is a kind of dog)
'leashed to protect property close to beach' is the wordplay.
'leashed' becomes 'bound' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'to protect' is an insertion indicator.
'property' becomes 'asset' (asset can mean an item of property).
'close to' indicates one should take the final letters (the close/ending of).
The final letter of 'beach' is 'h'.
'asset'+'h'='asseth'
'bound' enclosing 'asseth' is 'BASSET-HOUND'.
Can you help me to learn more?
(Other definitions for basset hound that I've seen before include "breed" , "Long-eared hunting dog" , "Sturdy hunting dog" , "one that hunts, naturally" .)
