When people talk about moving onward, they usually mean getting from one place to another, achieving something new, or taking steps towards a goal. For example, someone might say "We're moving onward with our plans" and that means they're making progress with their project. In other situations, you might hear "She took the next step onward in her career" which means she got promoted or advanced in some way. Sometimes people use onward to talk about traveling – for instance, "They went onward from Paris to Rome."
