Why is it called a chair?

Why the furniture used for seating is called a chair has to do with the history of language. The word comes from the 13th-century English word chaer, which in turn can be traced back to the Latin word cathedra, meaning seat. If that word reminds you of the word cathedral, it's no accident. The word cathedral gets its name from the fact that a cathedral is where the bishop of a parish has his seat. On 1stDibs, shop a wide range of chairs.
