TL;DR
A corner post is the fence post set wherever the fence line changes direction, built heavier than line posts because it resists pull from two directions at once. On wood and vinyl privacy fences it routes pickets or panels on both faces; on chain-link and wire fencing it takes the full tension of the stretched fabric, so it gets a larger diameter, a deeper concrete footing, and often diagonal bracing back to the adjacent posts.
What it means
A corner post is the fence post set wherever the fence line changes direction, built heavier than line posts because it resists pull from two directions at once. On wood and vinyl privacy fences it routes pickets or panels on both faces; on chain-link and wire fencing it takes the full tension of the stretched fabric, so it gets a larger diameter, a deeper concrete footing, and often diagonal bracing back to the adjacent posts. Underbuilt versions are why farm and chain-link fences slowly lean at the angles first.
