Isla, a trendy nature name inspired by land and water, is derived from the Spanish word isla, meaning "island," though it can also come from the name of the Scottish island of Islay. Isla first appeared in the Social Security Administration's top 1,000 for girl names in 1905 and returned in 1908 before spending the next 100 years off the list. It returned in 2008 and cracked the top-100 for the first time in 2017 before settling in the top-50 every year since 2020. It's not a coincidence that the name spiked in popularity one year after the release of "Hot Rod," a movie starring actress Isla Fisher.
