Heavenly or spiritual
Kieli is a rare name often associated with the Hawaiian word 'lani' meaning heaven or sky, though it is sometimes used as a modern variation of Keely. It carries a sense of lightness and ethereal beauty. In some contexts, it is also linked to the Finnish word for 'language' or 'tongue'.
