A tier is one level in a set of levels stacked on top of each other, or ranked from lower to higher — like the tiers of a wedding cake, the tiers of seats in a stadium, or the tiers of pricing for a phone plan ('the basic tier', 'the premium tier'). It's a useful word whenever things are organized in ranked levels, from things you can see (a cake) to things you can't (a company's ranking system).
