The Aettirs (clan – in the singular aett) are three groups of eight runes in which the ancient runaway alphabet of 24 letters is divided. This division is often mentioned in academic or esoteric texts on runes, but rarely has been questioned about the meaning of this triad, probably because the only citations of the use of aettir were in a numerological key or related to the practice of the “rune branch” twig runes or “rune tent” tent runes .
However, when painstakingly analyzed the Aettirs create a deep hierarchy in the rune system; and this hierarchy has a profound importance in the magical-esoteric system of runes. The Aetters seem to fit into a 3-degree system and seem to reflect the division of Indo-European tribal society (according to some contemporary enthusiasts).
The first aett is that of Freyja and represents the aspects of the nurse, the mother, the farmer, and the trader, and is contextualized in all those things that constitute the worldliness of life and being.
The Second Aett is Heimdall’s aett, and would represent the clan of warriors.
In this aett they make cases of crisis or need to temper the disposition of the person.
the third aett is Tyr’s aett, and would represent the head of the clan, the war-leader, also alluding to a priestly-like function of the same.
