Callissa is a variant of Calista, from the Greek meaning most beautiful. The spelling gives the name a softer, slightly more elaborate shape than its source, but the underlying sense of beauty remains clear.
It has the kind of classical heritage that makes it sound poised and intentional, even when it is rare in everyday use. Compared with Calista, Callissa feels a little more lyrical and a little less austere. That subtle shift makes it useful for parents who want a name with ancient resonance but a more individualized look. In modern naming, it reads as elegant, feminine, and lightly romantic, with a restrained sophistication that keeps it from seeming overly ornate.
