Aniko is of Hungarian origin, derived from the Hungarian word 'Anika', which means 'graceful'. It is predominantly used as a feminine given name and is composed of two elements: 'ani', meaning 'grace', and '-ka', a diminutive suffix. The name Aniko gained popularity in Hungary during the 20th century and has since become quite common throughout Central Europe.
The name Aniko experienced a significant increase in popularity from the late 1970s onwards, with a noticeable spike starting around the mid-1990s and reaching its peak in recent years (28 births in 2022). However, there were periods of relative obscurity during the early 1970s and again between the late 1980s and early 2000s.
