Meaning: “air; sky.”
Ilma comes directly from the Finnish word for air or sky. In Finnish mythology, Ilmatar was the name of a female air spirit who mothered Väinämöinen. She was said to have both male and female attributes but she was most often portrayed as a female. In Finnish, the suffix of -tar denotes a feminine spirit. She was also known as Luonotar (female nature spirit). Ilmatar was often the subject of the Finnish National Epic, Kalevala, which chronicles Finnish myths and legends.
As of 2010, Ilma was the 27th most popular female name in Bosnia & Herzegovina. In this case it may be a borrowing from the Italian form of Hilma..
A Finnish masculine form is Ilmari.
