Ar and the Sixteen-Rune Reduction

Ar is the tenth of the sixteen Younger Futhark runes, descending from Jera, the Elder Futhark's own twelfth rune, its core meaning of a good year or harvest carried forward closely from its Elder Futhark ancestor even as its sound value shifted to represent the vowel a in the Younger Futhark's economical system, one of the row's clearer cases of a rune's symbolic meaning surviving a reduction more completely than its precise phonetic value did.

Barnes' handbook notes that Ar's letterform in the Younger Futhark, a simplified form compared to the Elder Futhark's own more elaborate Jera sign, reflects a broader tendency across the sixteen rune reduction toward visually simpler, faster to carve shapes, consistent with runestones and everyday inscriptions across Viking age Scandinavia generally favouring economy of both sign inventory and individual letterform over the Elder Futhark's own somewhat more varied and elaborate shapes. Ar's position tenth of sixteen places it just past Isa in the row's fixed order, continuing the same general sequence both the Elder Futhark and the Younger Futhark share for their opening ten to twelve signs before greater divergence sets in toward each row's close.
