The meaning of this one seems obvious, but there's a twist: in Old Norse, it actually means 'cloud.' It's up to you to decide whether you're a happy, fluffy cloud; a grumpy thundercloud; a wistful mare's tail; or a mysterious mammatus cloud. You're probably all of the above.
Tove
Tove is short for Thor, which is the word for 'thunder.' You certainly have a lot of presence!
Sisu
Sisu means 'determination.' Maybe with all of that determination and focus, you would have been among the heroes of the great sagas!
Vieno
Ahhh, vieno means 'gentle.' Your soft heart and quiet nature bring peace to those around you.
Alva
Alva means 'elf'! You're a fun-but-mischievous being. No matter what you're up to--good or bad--you're certainly never boring!
Frey
The gods Freja and Freyr are the sources of this name. They are from a class of gods called the Vanir that was in charge of fertility, nature, seeing into the future, wisdom, and magic!
