Gladiola

The name Gladiola is derived directly from the Latin word 'gladiolus', which is a diminutive of 'gladius', meaning 'sword'. The flower known as the gladiolus, or 'sword lily', was named for its sword-shaped leaves. As a given name, Gladiola is quite rare and is a direct adoption of the flower's name.

Its usage as a personal name is relatively modern, likely emerging in the late 19th or early 20th century as part of a trend of using flower names for girls. While the flower itself has ancient roots, its use as a human name is not historically widespread or deeply embedded in any particular culture's naming traditions.
