Etymology

Origin of tier¹

First recorded in 1560–70; earlier also tire, tyre, teare, from Middle French, Old French tire, tiere “order, row, rank,” from Germanic; compare Old English, Old Saxon tīr, Old High German zēri “glory, adornment”

Origin of tier²

First recorded in 1625–35; tie + -er ¹

Explanation

A tier is a level or a layer. If you sit in the top tier of seats at a concert, you can see the whole stage and most of the audience — but you probably have to climb lots of stairs. A tier can describe a layer of ruffles on a dress, a section of seats in a stadium, or one layer of a fancy cake. You could also talk about a tier in terms of value or position. For example, the most popular, well-known actors might be considered part of the top tier, getting all the best parts. Tier originated from the Old French word tire: rank, sequence, or order.
