The "isa" rune, also known as "Isaz" or "Isa," is one of the runes in the Elder Futhark, which is the oldest known runic alphabet. Runes are ancient Germanic symbols used for writing, divination, and magical purposes. The "isa" rune represents the sound "i" or "ee" and is associated with the concept of ice. It symbolizes stillness, stagnation, and the need for patience. The rune is often interpreted as a sign of a temporary halt or a period of waiting, suggesting that progress or change may be delayed. It can also represent the need for inner stillness and reflection. In runic divination, the "isa" rune may indicate a need to be patient, to pause and reflect before taking action, or to be aware of obstacles and challenges ahead. However, interpretations of runes can vary depending on the context and the specific tradition or system of runic interpretation being used.
