Band maintaining safety in an estate, say (4,4)
I believe the answer is:
seat belt
'safety in an estate say' is the definition.
'seat belt' can be an answer for 'safety' (thesaurus). I am not sure about the 'in an estate say' bit.
'band maintaining' is the wordplay.
I cannot quite see how this works, but
'band' could be 'belt' (I've seen this before) and 'belt' is found within the answer.
The remaining letters 'seat' is a valid word which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for seat belt that I've seen before include "Safety strap worn in car" , "restraining device" , "Protective device to be worn in car" , "Protective strap in car" , "harness" .)
