An outward movement or direction is what's meant by "outward". When we move away from something or someone.
When we talk about going outward, it usually means moving away from a central point, like a city center. If you go on a hike and follow a trail that leads outward from the campsite, you're moving further and further away from the starting point. People who live in big cities often have to move outward to get some fresh air or find more space for their homes. Sometimes, we use "outward" to describe something like an outward appearance - how someone or something looks on the outside.
Outer; located towards the outside.
