Kaite is of American origin, derived from the name Catherine, which means 'pure' or 'clear'. It is often considered a variant spelling of Kate but also stands alone as a unique name. Kaite was quite popular in the late 20th century and has since maintained a steady presence among baby names.
"Kaite appears to have been a moderately popular name for newborn girls over the past few decades, with peaks in popularity occurring in the late 1980s and again in 2005."
