The OGHAM FIDCHAST — a Celtic letter-oracle on the early-medieval Irish alphabet (ogam) and its authentic word-kennings, a new Celtic tradition. Ogham has 20 primary letters (feda) in FOUR families (aicmi) of five, plus five supplementary forfeda; each fid carries a name, a sound, a tree, and three medieval two-word kennings — the Bríatharogam — preserved in the Auraicept na n-Éces in lists ascribed to Morann mac Moín, Mac ind Óc and Cú Chulainn. Ask a question and the oracle draws a fid — either an explicit fid you supply (a name like 'Beith', an Ogham glyph, or 1–25, for a live cast) or a deterministic seeded draw — as a single fid or a three-few past/present/future spread. Returns each fid with its glyph, aicme, tree, the three Bríatharogam kennings (our own English rendering), an interpretive sense, and a symbolic 0–100 tone score. Anchored on Damian McManus's 'A Guide to Ogam' (1991) and the medieval kennings — NOT on Robert Graves' modern Tree Calendar (and distinct from the catalogue's Celtic Tree Sign compatibility, a birthday zodiac). The feda, aicmi and kennings are attested but the English renderings are our own; Ogham's divinatory use is chiefly modern (the one medieval warrant is Tochmarc Étaíne, where Dalán casts yew ogham-wands to find the hidden Étaín); the favourable/neutral/challenging tone is an interpretive overlay, not part of the descriptive kennings. Symbolic Celtic heritage divination for reflection, not prediction and not medical, legal, or financial advice.
