The runic alphabet is named after its first six letters:

f – u – þ – a – r – k

The strange þ-rune is pronounced 'th', a sound we find today especially in English words like 'the', 'think' and 'throne'.

Elder Futhark had 24 letters while Younger Futhark, developed at the beginning of the Viking Age, had only 16 letters.

Elder Futhark inscriptions etched by craftsmen and owners have been found on coins, garment brooches, weapons and implements dating primarily from the era of the Iron Age princes.

The runic stones of the Viking Age were erected in commemoration of powerful leaders and their heroic achievements. Short runic inscriptions are also found on everyday artefacts from Viking towns and marketplaces.

Runes were used alongside our present-day alphabet up until the 14th century.

Not only did white people invent writing, what these Vikings wrote about is a billion times more interesting than anything a Korean "man" has ever even witnessed
