You're gonna have a tough time talking to others about your code if you don't agree on common terminology. Function invocation is just function invocation, it doesn't say anything about the form of the parameters or composition. Dependency injection is a well known and commonly understood method of facilitating decoupling and composition by passing a function's dependencies as parameters. From your comments you're talking about the second, but refusing the name, for... reasons?

“Dependency injection” is just a term for providing a function or method with its dependencies rather than making the function go and gather them itself.

It’s (typically) done through parameters, but it’s still more specific than just invoking a function. It describes how that function was written and the reasoning for certain parameters. To the other commenter’s point, you’ll have a hard time communicating about your code with other developers if you refuse to use the term dependency injection just because you don’t like OOP.

Di is just good functional practice. I'm not sure it's a super importent idea to someone who knows how to write a good function.

Edit: "a function do one thing and its operands should be passed as arguments" for the OO world.
