Isa (ᛁ) is the eleventh rune in the Norse Futhark runic alphabet and represents the sound I. It also represents the concepts of ice, moments frozen in time, and stagnation.
Isa is also the third rune in the second aett. The Norse runes are divided into three eight-rune families, which represent distinct themes. The second aett is ruled by Heimdall and represents challenge, transformation, and disruption.
In divination, the Isa rune suggests that things have ground to a halt. This often feels like a frustrating setback, but it can also be that time of rest that you need for changes you have made to sink in and start to take effect. It is what you need to strengthen yourself to burst into motion again.

The Isa rune is linked with Niflheim, the primordial world of cold and mist. In the beginning, when there was nothing but emptiness in the great void of the Ginnungagap, cold mist from Niflheim seeped into the gap and mixed with heat from Muspelheim, the realm of heat, to create the primordial ooze from which all life emerged.
Later, when Odin and his brothers organized the cosmos, Niflheim formed the earth for the great world tree Yggdrasil. It was home to the wells that fed the tree, and was permeated by the roots of the tree. The great dragon Nidhoggr lives among the roots. It also became the underworld realm, where Hel ruled over Helheim, but it was also the location of the Well of Wisdom. Niflheim reflects the idea that while the cold can feel stifling and stagnate, it is actually a place of profound depths that can feed life.

The Isa rune is also linked with the goddess Skadi, who was a giantess considered the patroness of winter, hunting, and skiing. It can also be linked with Ullr, a mysterious god known as the son of Sif who also wandered the winter wilderness as a hunter and skier. He was also the god of oaths.
Isa Rune Poems
Our understanding of the Old Norse runes comes from rune poems, which provide explanatory stanzas for each letter. There are Norwegian, Icelandic, and Anglo-Saxon poems for the Isa rune.
Norwegian
Ice is called the broad bridge; the mind man must be led.
Icelandic
Ice is bark of rivers and roof of the wave and destruction of the doomed.
Anglo-Saxon
Ice is very cold and immeasurably slippery; it glistens as clear as glass and most like to gems; it is the floor wrought by the frost, fair to look upon.
These poems highlight the dangers of winter in northern climates. Not only is it a time of food scarcity, but frozen lakes and avalanches represent real danger. But while dangerous, ice and snow are also things of beauty. And when the snow melts, the spring will emerge, revealing the life-giving aspects of ice.
Isa in Divination

In divination practices, the Isa rune can have several meanings:
- Stagnation and Inactivity – The Isa rune can suggest that you have reached a plateau that will take time to push through, or worse, that you have hit a brick wall and you will need to change course.
- Patience and Growth – The rune can suggest that now is a time to be patient and appreciate and consolidate the growth that has led you to where you are before trying to push for more. If not, you could find yourself facing even nigger setbacks due to burnout.
- Detachment – The Isa rune can also show up when you are feeling emotionally “cold” and detached from the things that should matter. It can be a call to reexamine your priorities and how you are spending your energy to rediscover your spark for life.
The position of the runestone in relation to the reader influences the reading:
- Upright: The Isa rune often suggests that you have reached a period of pause, and while it may be frustrating, it is necessary, and you should make the most of the calm before the storm.
- Merkstave (reversed): The Isa rune does not have a reversed reading because it appears the same both upright and reversed.
- Sideways: In this case, the Isa rune can point towards things that are draining your energy and causing you a period of stagnation.
How it should be read also depends on where it falls in relation to other runes.
- Combined with Fehu – a freezing of your financial assets and the need to tighten belts while issues are resolved
- Combined with Hagalaz – suggests an extended period of hardship that will not be resolved quickly
- Combined with Jera – indicates a period of hardship before a major breakthrough and assures you that your current sacrifices will be worth it
- Combined with Sowilo – indicates that you are about to experience a dramatic period of growth following stagnation
- Combined with Laguz – suggests that your emotions and energy are blocked and you need to work through something to let your emotions flow again
