German, another language with gendered nouns, has Riese and Riesin for male and female giants, respectively. Oddly, German uses the same word, Zwerg, to refer both to IRL people with dwarfism and to imaginary people who are Tom Thumb-sized. And yes, a female “dwarf” is a Zwergin.
(Tom Thumb is Daumling (Thumbling) in the original German Kinder- und Hausmärchen by the Brothers Grimm)
