1.  The 11th rune of the Elder Futhark, representing the letter i. As the name of this rune implies, ISA signifies a cessation of activities—a freeze. All plans should be put on hold for the moment to be resumed at a more auspicious time.

2.  Isa is the third rune of the second aett. Like the first two runes in this aett, Isa is also associated with an element—the element of ice. Water is fluid; ice is solid and static. Isa therefore represents the principle of preservation and resistance to change.
