It is a pretty debated subject among historians and scholars, and one where a lot of history has been lost, so forgive me if I've missed the latest research on the subject. Don't take my word as a gospel of truth. But the basic idea is very similar to the Finnish one, and the soul is made up of several "parts" or "energies". There is the Likamr, which is simply the physical matter, the body. When one dies and the other parts of the soul leaves, the Likamr is simply the corpse. Then there is the Hamr, which is ones physical appearance. Note that the Hamr is different from the physical body. The Fylgja, which translates as "follower" is a spirit that often appeared as an animal and can, roughly speaking, be compared to the Finnish idea of the Luonto, but it has clear parallels also to the Hamingja and is associated with a persons inherited luck. Maegen/Hamingja, roughly described as the inherited might or luck of an individual, passed down the family line. They're different concepts, but similar enough for an English audience. The Wyrd, a persons amassed past actions that shapes the person, a little bit like Karma actually, also described as ones life thread. There is Önd, the breath, and the final life force given to a baby upon birth. The Hugr and Munr, the will/intent of a person and the memory of a person. There is also the Wod, the "divine madness". So, that's a lot of parts. Lets go onto explaining them.
The Likamr (also known as the Lich) is pretty much covered. The physical body. The Hamr is where it gets interesting. Hamr translates roughly as "home", and is the boundaries that makes a spirit an individual and keeps it all together. It is the reason why a ghost, or someone who travels outside of their body, might look like a person even though they've left the physical stuff behind. A powerful mage can change their Hamr, like an astral traveler who borrows an animal form. But it could also be the physical appearance of a person, hence how truly powerful mages could be physical shapeshifters.
The word "Fylgja" can refer to different things, but in this topic it refers to an animal spirit that was an individuals mirror image, guardian, or counterpart. The word means "Follower", and a child received their Fylgja when they were nine days old, at the same day that naming ceremonies were traditionally held. A person often share personality characteristics with their fylgja, a sly and cunning person could have a fox fylgja, while a ferret fylgja might follow an overly excited and very hyper individual. Some sources claim they are the opposite gender of their human, others that it was always female.
The wyrd.. well, the wyrd (or the Urdr) is a little bit like a persons Karma, or fate. The weight of your actions, the past that you always carry with you. There is an idea that there is a great weave of fates, a fabric, and a Wyrd is like a persons individual thread, which we will spin and weave through actions. Think of a spindle; you have un-spun wool in one end, you give the spindle a twirl, and end up with a thread around the other end. Based on how you do it, you could end up with thick thread that might be great for knitting socks but bad for other purposes; you might end up with a thin and delicate thread that will make for great embroidery material, but it will make for lousy socks. Or, if you're not paying attention, you could end up with some pretty sloppy thread that isn't the best for anything really. But the thread can never be undone. Whatever your actions were, however you spun the thread, it is there forever, and will affect you. The idea is that like attracts like; so if you are a thief, you will likely attract other thieves into your life. If you are an honorary person, you will meet with other honorary people. Although the wyrd can never be changed, a bad one can be "canceled out" by taking better actions in the future and fixing your mistakes. This means that the old Norse did not believe in luck as a random force; rather, a person with good luck had a respectable Wyrd and Örlog, they accumulated their good luck through their lifetime.
Some scholars claim that the Wyrd begins at the childs ninth night of living, the same night it receives its Fylgja. It is then that it counts as a complete human being, soul-wise.
The Hamingja was the accumulated "luck" or wyrd/örlog of a family line. This is like the collective version of multiple peoples wyrd, that a child inherit from their ancestors. Hence (or at least, this is my personal interpretation of it) why it is very common to see children inherit their parents/family's character flaws, like alcoholism, or an angry disposition, or whatever have you; they inherit their parents Hamingja, and will pass it down the line until the unresovled issue with the Wyrd is resolved through right action. BUT it could also be a good thing, and a person can inherit great luck from their relatives. The Hamingja can be received at the same time as the Fylgja and when a child is accepted into the family through the naming ceremony, or whenever an older relative dies and pass their Hamingja on to the person of their choice. One saga tells of an adult man who had a dream of a huge giantess taking up residence in his home, which he interpreted as the death of ones of his relatives, and his large amount of luck now passing down to him, so it is not limited to children at all.
The Önd, the breath, given to a child at birth. Connects the Likamr to the outside world.
And lastly we have the Wod (the Hugr and Munr, thought/intent and memory, explain themselves if you ask me). Think of this as... hmm.. everything in the mind which is not rational thought. A baby doesn't have rational thought yet, but they have Wod. Creativity, spirituality and such things are connected with Wod.
If one want to have a more 'simplified' soul overview, I would limit the most basic parts to the ones mentioned in the human creation myth, where Oden give breath and spirit (önd), Hönir gave common sense and thought (could be the Hugr and Munr, and/or the Wod), and Lodr gave blood and color (the Hamr). Those might be considered the 'essence' of a human soul. The other parts are definitely of great importance to the life of a human as we know it, but perhaps they are not the very *essence* of a soul complex.
