Idad

What is Idad?

Idad (pronounced approximately as its Latin equivalent, I) is one of the letters of the ancient Ogham alphabet, the edge-carved writing system used in early medieval Ireland and Britain. It belongs to the Aicme Ailme — one of five groupings that make up the full 25-letter Ogham script.

In the traditional Celtic tree calendar associated with Ogham, Idad is linked to the Yew tree. Each Ogham letter carries not just a phonetic value but a natural symbol — a feature that makes Ogham unique among ancient European writing systems.

How to Write Idad

In the Aicme Ailme, strokes are cut as notches through the central stem line (the druim) — these are the vowels.

Ogham is traditionally written bottom-to-top along the edge of a standing stone. In modern horizontal use — as seen in tattoos, jewellery, and digital text — the script reads left-to-right.
