choir (n.)

c. 1300, queor "part of the church where the choir sings," from Old French cuer, quer "(architectural) choir of a church; chorus of singers" (13c., Modern French choeur), from Latin chorus "choir" (see chorus). Meaning "band of singers" in English is from c. 1400, quyre. Re-spelled mid-17c. in an attempt to match classical forms, but the pronunciation has not changed.
