Sierra
Meaning
mountain range
The story
Sierra means "mountain range" in Spanish, the kind with jagged peaks, and America heard it as scenery first and a name second. The register shows a trickle at midcentury, 144 girls in the 1940s, then the landscape decades arrived: 787 in the 1970s, 8,846 in the 1980s, and a remarkable 43,638 across the 1990s, when Sierra ran with Savannah and Cheyenne in the great atlas-browsing wave of American naming. The 2000s held 34,534 before the tide went out, 9,272 in the 2010s and 3,241 so far this decade. The name still does everything that made it work: two syllables that sound like open country, a Spanish word American English already uses for its own mountains, and the Sierra Nevada itself standing behind it, most of it in California with a spur into Nevada. Names borrowed from maps age like the places do, which is to say slowly.
