Yes, you’re right -- I found one more place where the term should be updated. Everything else seems fine

[serhiy-storchaka]

I think there are more:

This method takes one parameter,

Signatures themselves are restricted to the top level parameters expected by a
method. For instance if a method expects one array of structs as a parameter,

And most likely:

a client can call methods with parameters

Method has parameters, but it expects and takes arguments.
