loanword
"Kindergarten" comes from German, literally combining "Kinder" (children) and "Garten" (garden) to evoke a nurturing space where young children grow like plants in a garden. English absorbed the word wholesale, including its capitalization conventions in some styles, as part of broader borrowing from German educational vocabulary.
French and Arabic are unrelated to this particular word's origin; while English has borrowed heavily from both languages elsewhere, "kindergarten" specifically traces directly and exclusively to German roots.
English has pulled in a surprising number of German words beyond kindergarten, including "angst" (anxiety/dread), "zeitgeist" (spirit of the times), and "wanderlust" (desire to travel), each retaining a distinctly German philosophical or emotional flavor even in English use.
