Ina

Ina originated as a short form of longer names ending in the suffix -ina, such as Katharina, Regina, and Wilhelmina, and came into independent use across Germanic and Scandinavian languages. The suffix itself derives from Latin -ina, a feminine diminutive or adjectival ending commonly attached to names throughout medieval Europe. The name spread widely in English-speaking countries during the nineteenth century, partly through the popularity of longer source names being shortened in everyday use. Related forms include Ena, Ines, and the extended variant Ines, while Wilhelmina and Regina remain among its most frequent source names.
