About the name Kale
Kale belongs to the English & American tradition. Its roots are documented, even though its precise meaning is not recorded in the standard references — an honest gap we prefer to a confident guess.
In the United States, Kale first appears in Social Security records in 1917. It climbed to its best-ever rank of #504 in 2008, and in 2024 18 babies received the name — 7,368 in total since 1880. Those are the official counts, not estimates.
