It was in use for epigraphy during the 3rd to the 8th centuries. It is not continued in the Younger Futhark, disappearing from the Scandinavian record around the 6th century, but it survived in the Anglo-Saxon Futhorc, and expressed the Old English œ phoneme during the 7th and 8th centuries. Its name is attested as ēðel in the Anglo-Saxon manuscript tradition.

Name and etymology
The Common Germanic stem ōþala- or ōþila- "inherited estate" is an ablaut variant of the stem aþal-. It consists of a root aþ- and a suffix -ila- or -ala-. The suffix variant accounts for the umlauted form ēþel. Germanic aþal‑ had a meaning of (approximately) "nobility", and the derivation aþala‑ could express "lineage, (noble) race, descent, kind", and thus "nobleman, prince" (whence Old English atheling), but also "inheritance, inherited estate, property, possession". Its etymology is not clear, but it is usually compared to atta "father" (c.f. the name Attila, ultimately baby talk for "father").
The term oþal (Old High German uodal) is a formative element in some Germanic names, notably Ulrich and variants; , the stem aþal is more frequent, found in Gothic names such as Athalaric, Ataulf, etc. and in Old High German names such as Adalbert, 
Unrelated, but difficult to separate etymologically,[clarification needed] is the root aud- "wealth, property, possession, prosperity"; from this root are names such as Edmund and other English names with the ed prefix (from Old English ead), German Otto and various Germanic names beginning with ed- or od-. Possibly related is euþa, euþu a word for "child, offspring" (attested in Old Norse jóð, and possibly in the name of the Iuthungi).
Odal was associated with the concept of inheritance in ancient Scandinavian property law. Some of these laws are still in effect today, and govern Norwegian property. These are the Åsetesrett (homestead right), and the Odelsrett (allodial right).
Elder Futhark o-rune
The o-rune is attested early, in inscriptions from the 3rd century, such as the Thorsberg chape (DR7) and the Vimose planer (Vimose-Høvelen, DR 206). The letter is derived from a Raetian variant of the letter O. The corresponding Gothic letter is 𐍉 (derived from Greek Ω), which had the name oþal.
Wolfgang Krause (1964) has speculated that the o rune is used as an ideograph denoting possession in the Thorsberg chape inscription. The inscription has owlþuþewaz, read by Krause as O[þila] - W[u]lþu-þewaz "inherited property - the servant of Wulþuz".
The odal rune is found in some transitional inscriptions of the 6th or 7th century, such as the Gummarp, Björketorp and Stentoften runestones, but it disappears from the Scandinavian record by the 8th century. The Old Norse o phoneme is now written in Younger Futhark with the same letter as the u phoneme, the Ur rune.
The Anglo-Saxon runes preserve the full set of 24 Elder Futhark runes (besides introducing innovations), but in some cases these runes are given new sound values due to Anglo-Frisian sound changes. The odal rune is such a case: the o sound in the Anglo-Saxon system is now expressed by ōs ᚩ, a derivation of the old Ansuz rune; the odal rune is now known as ēðel (with umlaut due to the form ōþila-) and is used to express an œ sound, but is attested only rarely in epigraphy (outside of simply appearing in a futhark row). Epigraphical attestations include:
- the Frisian Westeremden yew-stick, possibly as part of a given name Wimod (Wimœd)
- the Harford (Norfolk) brooch, dated c. 650, in a finite verb form: luda:gibœtæsigilæ "Luda repaired the brooch"
- the left panel of the Franks Casket, twice: twœgen gibroþær afœddæ hiæ wylif "two brothers (scil. Romulus and Remus), a she-wolf nourished them".
The Anglo-Saxon rune poem preserves the meaning "an inherited estate" for the rune name:
The Odal rune was the emblem of ethnic Germans (Volksdeutsche) of the 7th SS Volunteer Mountain Division Prinz Eugen operating during World War II in the Nazi Germany-sponsored Independent State of Croatia. The Odal rune has been used by the Neo-Nazi Wiking-Jugend in Germany, and in South Africa by the Anglo-Afrikaner Bond, the nationalist, and heavily subjugated, Boer minority organization Boeremag, and the Blanke Bevrydingsbeweging.
The Odal rune was used as one of the protection runes of the Shadow Hunters in the film adaption of the first in the series of Cassandra Clare books City of Bones. It was shown prominently on the character poster for Izzy, who wears it on her collarbone. It was also used throughout promotional material to highlight the stories themes of family and inheritance.
