Kaydence is an American respelling of Cadence, the English word for a "rhythm" or a "flow of sound" that goes back to the Latin cadere, to fall. The word became a first name only around 2000, and the K spelling rode the same wave as Kaylee and Kayden. Kaydence entered the top 1000 in 2003, peaked at number 254 in 2009, left the top 1000 again in 2023 and ranks number 1292 in 2025.
