tier
TEER
/tɪər/
One of a series of rows or levels of a structure, or a level of authority, status, or privilege in a system.

The story behind the word. This word climbed up to us from the battlefield. It comes from the Old French tire, meaning 'rank, row, or sequence,' which was often used to describe rows of soldiers or layers of stones in a wall. In modern loyalty programs, these rows have become vertical ladders, where customers climb from one level of privilege to the next.
