The kennings for "Ébhadh" point to the sound "éo" or "é", which is also the word for "salmon". The name appears modelled after "Eadhadh" and "Iodhadh". The kennings for "Ór" point to the word "ór" "gold" (cognate to Latin "aurum"). The kenning of "Uilleann", "great elbow", refers to the letter name. Since the Ogham alphabet dates to the Primitive Irish period, it had no sign for in its original form and the letter "Pín" was added as a letter to express it. McManus states that the name "Pín" was probably influenced by Latin "pinus" ('pine'), but a more likely explanation is that it derives from Latin "spina" ('thorn'), as the kennings indicate a tree or shrub with sweet tasting fruit (therefore not a pine). According to Kelly (1976) the name "spín" ( deriving from the Latin ) appears in the Old Irish tree lists as meaning either gooseberry or thorn, so the medieval glosses may be correct on this occasion. The name "Eamhancholl" means "twinned "coll"", referring to the shape of the letter (ᚙ resembling two ᚉ), and also perhaps referring to its sound being similar to that of "coll" ( being a fricative variant of ). The Bríatharogam kenning "groan of a sick person" refers to a value "ch" [x, predating the decision that all five "forfeda" represent vowels.
