An Anglo-Saxon futhorc rune entry records a single character of the extended runic alphabet used in early medieval England and Frisia, its documented shape, its sound value and, where a source survives, the short verse tradition attached to its name. The Old English Rune Poem preserves stanzas naming and explaining a large run of these characters, giving scholars a documented near contemporary account of what each rune's name was taken to mean rather than a later reconstruction alone.
An entry records a rune's documented sound value and name, its attested position within the futhorc row, and the poem's own stated verse where one survives for that rune, since the poem's explanations are themselves centuries removed from the futhorc's earliest use and are recorded as a documented later reading rather than as the rune's single original meaning.
Where a rune's name or verse differs across surviving manuscript traditions, an entry records that documented variation honestly, since the futhorc survives through a genuinely small number of manuscript witnesses, each with its own transmission history worth noting rather than silently harmonized into one account. An entry also records where a rune's attested inscriptional use, on a coin, a stone or a small object, agrees or disagrees with the poem's later literary explanation, since the two kinds of evidence come from different centuries and different purposes and are worth keeping separate rather than folded into one flat description.
