The evolution of the rune in the elder futhark during the centuries.

The k-rune ᚲ (Younger Futhark ᚴ, Anglo-Saxon futhorc ᚳ) is called Kaun in both the Norwegian and Icelandic rune poems, meaning "ulcer". The reconstructed Proto-Germanic name is *Kaunan. It is also known as Kenaz ("torch"), based on its Anglo-Saxon name.

The Elder Futhark shape is likely directly based on Old Italic c 𐌂 / Latin C. The Younger Futhark / Futhorc shapes have parallels in Old Italic shapes of k 𐌊, Latin K (compare the Negau helmet inscription). The corresponding Gothic letter is 𐌺 k, called kusma.

The shape of the Younger Futhark kaun rune (ᚴ) is identical to that of the "bookhand" s rune in the Anglo-Saxon futhorc. The ᚴ rune also occurs in some continental runic inscriptions. It has been suggested that in these instances, it represents the ch /χ/ sound resulting from the Old High German sound shift  (e.g. ᛖᛚᚴ elch in Nordendorf II).

Rune Poem:	English Translation:
Old Norwegian ᚴ Kaun er barna bǫlvan; bǫl gørver nán fǫlvan.	Ulcer is fatal to children; death makes a corpse pale.
Old Icelandic ᚴ Kaun er barna böl ok bardaga [för] ok holdfúa hús. flagella konungr.	Disease fatal to children and painful spot and abode of mortification.
Anglo-Saxon ᚳ Cen byþ cwicera gehwam, cuþ on fyre blac ond beorhtlic, byrneþ oftust ðær hi æþelingas inne restaþ.	The torch is known to every living man by its pale, bright flame; it always burns where princes sit within.
Notes: The Icelandic poem is glossed with Latin flagella "whip". The Anglo-Saxon poem gives the name cen "torch".
