 When hinting based on a Protocol there can often be unexpected complexities.
 Consider passing in an instance of a class with an attribute hinted `str` while the protocol hints it as `Union[str, int]`.
-It is common to expect that `str` satisfies `Union[str, int]` and to be throughly confused by mypy's complaint that it does not.
+It is common to expect that `str` satisfies `Union[str, int]` and to be thoroughly confused by mypy's complaint that it does not.
 The hazard here is that since the function receiving the object thinks the attribute can be either a `str` or an `int` it may decide to assign an `int` to it.
 The protocol says this is ok.
 A good solution for many cases is to hint that attribute as being read only on the protocol.
