[ 3 syll. sier-ra, si-e-rra ] The baby girl name Sierra is also used as a boy name, though it is far more popular for girls. It is pronounced Siy-EH-R-aa- †. Sierra has its origins in the Spanish language and it is used largely in English. The name is derived from the Spanish word sierra, in reference to a mountain range with jagged peaks, and favored for its allusion to the beauty of nature. It has recently been adopted by English speakers, and its use promoted in the USA after the Ciara brand of perfume was introduced by Revlon in 1973. Although the forms starting with 'C-' are pronounced with a hard 'K-' in Irish, the influence of the perfume brand, which is pronounced like Sierra, has led to many US speakers using the soft 'C-' pronunciation. In the USA, the Sierra Club is also well-known as the largest grassroots environmental organization.
