What is Younger Futhark?

Younger Futhark is the reduced runic alphabet used across Scandinavia during the Viking Age, roughly 800 to 1100 AD. It shrank the older 24-rune Elder Futhark down to just 16 runes, so a single rune often represented several related sounds.

Why do different letters produce the same rune?

Sixteen runes cannot cover every Latin sound, so the script merged distinctions. The same rune served voiced and unvoiced pairs and similar vowels: B and P share one rune, T and D share another, and the same rune covers U, O, V, W, and Y. This faithfully reflects how Younger Futhark was actually written.

Which variant does this tool use?

It uses the long-branch (Danish) Younger Futhark, the most widely attested form, rendered with the standard Unicode Runic block. The short-twig (Swedish-Norwegian) variant uses different glyph shapes for some runes but the same sound system.

Is this a reversible cipher?

Not perfectly. Because several Latin letters collapse onto one rune, you cannot always recover the exact original spelling from the runes alone. Transliteration back to Latin requires context, just as it did for medieval readers.

Will the runes display on my device?

The runes use the Unicode Runic block (U+16A0 to U+16FF). Most modern systems include a font that covers it, but on older devices some runes may appear as empty boxes if no runic-capable font is installed.

Younger Futhark Rune Encoder

The Younger Futhark is the 16-rune alphabet that Scandinavians used through the Viking Age. It is a streamlined descendant of the 24-rune Elder Futhark, and the sharp reduction means a single rune often stands for several related sounds. This tool transliterates Latin text into those 16 runes by sound.

How it works

Each Latin letter is mapped to the long-branch rune that best matches its sound, with deliberate merges where the script had no separate rune:

f ᚠ   u/o/v/w/y ᚢ   th ᚦ   a ᚬ   r ᚱ   k/g/c/q ᚴ
h ᚼ   n ᚾ   i/e/j ᛁ   a(as) ᛅ   s/z ᛋ   t/d ᛏ
b/p ᛒ   m ᛘ   l ᛚ   R/-z ᛦ

The digraph th is read as the single rune Thurs (ᚦ) before falling back to letter-by-letter mapping, matching how the sound was written.

Example and notes

The name THOR transliterates to ᚦᚢᚱ — the th becomes Thurs, o shares the U-rune, and r is Reidh; the lack of a distinct O is authentic to the period. Because B and P, T and D, and several vowels each collapse onto one rune, the transliteration is not perfectly reversible: a medieval reader, like this tool, relied on context to recover the intended word.
