There are many versions of the runic alphabets. Each has variations in names, shapes, esoteric meanings and magical uses. One should not mix futharks, or the intent or meaning becomes confused. The Elder Futhark, the Anglo-Saxon Futhorc, and the Younger (or Scandinavian) Futhark are the most frequently seen versions of the runic alphabets in use today.
The runes are broken into three sections or groups of eight, called aett (aettir, plural). This helps one to remember their order, and later, you will see, has significance in magical uses.
First the rune name is given, then its phonetic value, its symbolic image, and finally the esoteric meaning used in divination. Rune users disagree on whether or not to place a different meaning on a rune that falls in an inverted or reversed position. Some runes look the same upside down and right side up. These cannot be "reversed". Nevertheless, any of the runes may appear as a "merkstave" (which literally means "dark stick" and implies a "dark" meaning), depending on how the runes are cast. Note that a "reversed" or "merkstave" meaning is not the opposite of its primary meaning, but usually has a more negative connotation.
