A letter of the Runic alphabet, present in the Elder Fuþark (ᛇ) and the Anglo-Saxon Fuþorc (ᛇ, called ēoh) representing /eo/ or /eːo/ and associated with the yew.
Etymology
Two variants of the word are reconstructed for Proto-Germanic, *īhaz (*ē2haz, from the Proto-Indo-European root *eikos), continued in Old English as ēoh and īh, and *īwaz (*ē2waz, from the Proto-Indo-European root *eiwos), continued in Old English as īw (whence yew). The latter is possibly an early loan from the Celtic.
