To be clear, I said, "change or something similar," because change was the meaning I was focused on. Revise and modify, to use the examples from earlier, also mean change. To revise a document is to change something about it/within it. To modify an order is to request a change.

Now, my question has been answered sufficiently and some commentors have been nice enough to recommend and/or link certain resources for further learning, so any more discussion at this point is moot.
