Ogham is an Early Medieval alphabet used to write early forms of the Irish language.

It served two main purposes throughout history. First, it was used for "orthodox" inscriptions from the 4th to the 6th centuries AD. These were usually carved into stone monuments. Second, it was used for "scholastic ogham" from the 6th to the 9th centuries. This later version recorded names in many languages. These included Old Norse, Welsh, Latin, and possibly Pictish.

The mechanism of the Ogham script relies on a system of strokes. The alphabet is organized into four distinct groups. Each group contains five letters, totaling twenty original characters. There are also five supplementary letters known as forfeda.

These letters are often carved along a central line. This line can be a straight edge on a stone pillar. The strokes are placed in different directions relative to this line. Many people call it the "Celtic tree alphabet." This name comes from the kennings, or nicknames, used for the letters. These names often refer to various trees and plants.

Scholars have proposed several different theories regarding the origins of Ogham. One school of thought suggests it was a cryptic alphabet. Scholars like James Carney and Eoin MacNeill argued it was a secret code. They believed Irish scholars or druids created it for political or religious reasons. This would allow them to communicate secretly during the Roman occupation of Britain. Another theory suggests it was created by early Christian communities around AD 400. These groups may have wanted a unique script for the Irish language. The Latin alphabet might not have captured all the specific sounds of Primitive Irish.

A third hypothesis involves a system of finger signals. R. A. S. Macalister suggested druids in Cisalpine Gaul used these signals around 600 BC. He believed these signals were later turned into a written script. However, most modern scholars reject this specific idea. They argue the letters were designed specifically for the sounds of Primitive Irish. A fourth idea suggests the letters grew from a numerical tally system. This system would have been based on the numbers five and twenty.

Some researchers also believe the script was modeled on the Latin alphabet. Others suggest it might have been inspired by Germanic runes or even the Greek alphabet.

We can find significant evidence of Ogham through surviving stone monuments. There are roughly 400 orthodox inscriptions remaining in Ireland and western Britain.

The majority of these are located in the southern province of Munster. Specifically, the counties of Cork and Kerry hold 60% of all Irish ogham stones. Outside of Ireland, the largest concentration is found in Pembrokeshire, Wales. Many of these stones are bilingual. They feature both Ogham and Latin text side by side. These inscriptions mostly consist of personal names. They may also serve as marks for land ownership.

Ogham also exists within the realm of Irish folklore and legend.

One legend claims the king Fenius Farsa invented it. He supposedly created the script after the fall of the Tower of Babel. He is said to have gathered the best parts of many languages to create Goidelic. Another tradition attributes the invention to the figure Ogma. Ogma was a master of speech and poetry. He reportedly created the system to distinguish the learned from the uneducated. In these stories, the letters are named after his many scholars. In other versions, they are named after trees, such as the birch.

Today, Ogham serves as a vital link to the linguistic history of the Celtic people. It provides a window into the transition from Primitive Irish to Old Irish. This linguistic shift occurred around the 6th century. By studying the specific phonemes in the script, researchers can track how languages change over time. Even though some letters, like "H" or "Z," were not used in Irish, they remain in the system. These unused letters suggest the alphabet may have been used on wood or other perishable materials before it was carved in stone. This helps us understand how ancient writing systems evolve and adapt to new cultures.
