Ior is a dipthong ‘io”

Anglo-Saxon Rune Poem (from ragweedforge.com)

Ior is a river fish and yet it always feeds on land;
it has a fair abode encompassed by water, where it lives in happiness

Ior is the rune of boundaries, as the dual expression of what it is to be the boundary itself, and also in establishing that boundary. It is often associated with Jormungard, the World Serpent, which defines the boundaries the of Midgard, protecting it from what lies outside, but also keeping what is inside, in. The nature of a boundary however, is that it encompasses both things, the in and out, and partakes of the natures of both, but it is also neither. In that sense, Ior is the liminal rune, and is associated with people who live on the boundaries, transgendered peoples of all types.

In a reading Ior signifies boundaries and limits. Sometimes those boundaries need to be established and clarified, other times, it is embracing them so they can be understood and surpassed.

Ior is the sound io

Ior is a rune of boundaries and liminality. Liminality, from the word liminal, has a definition of being an intermediate state, phase, or transition. It is when you exist between two things. It is taken from the latin word for threshold. If you stand on the threshold of a door, you are liminal because you are neither inside nor outside, but intermediate, between those states. The river fish is a fish, but it feeds on land. It exists in a constant liminal state because it encompasses both of those features. Ior is speaking to that liminal state. You might be a liminal person yourself, or transitioning between two states, and are at an intermediate phase, where you are taking of both, but beholden to neither.

Ior is translated river-fish, often interpreted as being a beaver or fresh water otter, as by earlier mindset, they were considered a fish. It is also often associated with the World Serpent, Iormungand.
Today, the meaning for me has been about boundaries, limits and, as I wrote in my divination journal, parameters. Sometimes, you just need to experience your limits and get a sense of your boundaries, and live within them, accept them, and understand them.. You don’t always have to push yourself. Sometimes, doing so will work against you.

Ior is the combined sound of io. I don’t think it has much use in modern language.

Ior translates as the river fish. Most academic translations refer this to a beaver, as at the time this was written beavers (and otters) were considered very peculiar fish. It may have also referred to the otter.

In most systems, Ior is considered to metaphysically connect with Jormungand, the world serpent of Northern myth, who was one of the children of Loki and Angrboda. Some interpreters consider this a rune of happiness(because of the ending of the stanza) but others consider this the rune of boundaries, and yet also synthesis. It all has to do with the meaning of boundaries. A boundary separates one thing, from another. Yet the boundary is both things. It is In and Out, Fire and Ice, That Which is and That Which isn’t, that which can be, and that which must not be. Typically in a reading, it shows the encounter with boundaries and limits though, and only rarely is the quality of that liminal state presented.
