EN (English)Ogham
Edad has no recoverable meaning. No Old Irish word stands behind it, its kennings are the most textually corrupt in the corpus, and the likeliest account is that it was coined to rhyme with Idad because the vowel series had a slot to fill. The aspen came afterwards, from a tree whose Irish name means trembling, and the grief attached to it was reasoned backwards from there. Today something sits on your plate because a structure required it rather than because anybody needed it done. Name it as what it is, and skip the step where you work out a reason it matters.
