Maybe.
When I was in the US, I had this dish called biscuits and gravy, what we would probably refer to as scones in white sauce.
Biscuits are generally sweet and crackers generally savoury and a wafer can be either, though all three are texturally different.
Crackers and certain biscuits and wafers are often served with cheese after a meal, generally known as cheese and biscuits.
Bonnet and hood have a certain connection, but I'm not sure why we refer to the trunk as the boot.
Though these days, the boot has largely been superseded by the hatch back.
