Say It Right: Mabinogi
How to say Mabinogi — "mab-in-OG-ee," with a hard g. The Four Branches of medieval Welsh tale, and why the title's meaning is debated.

Mabinogi, the great cycle of medieval Welsh tales, is said 'mab-in-OG-ee' - four syllables, stress on the third, a hard g as in 'got.' Strictly it names the Four Branches (Pwyll, Branwen, Manawydan and Math). The longer title 'Mabinogion' is not medieval; it was popularised in the nineteenth century by Lady Charlotte Guest. The word's meaning is genuinely uncertain.

The great cycle of medieval Welsh tales is said “mab-in-OG-ee” — four syllables, with the stress on the third, OG. Every letter is sounded; the g is hard, as in “got,” and the final i is a clear “ee.”
You will also hear the longer form Mabinogion (mab-in-OG-ee-on). It is worth knowing that this plural title is not medieval: it was popularised in the 19th century by Lady Charlotte Guest, whose translation introduced the tales to English readers. Strictly, Mabinogi refers to the “Four Branches” — the linked tales of Pwyll, Branwen, Manawydan and Math.
Meaning is genuinely uncertain, and it is fair to say so. The word may derive from mab (“son, boy”), suggesting “a tale of youth” or “a story of a hero’s boyhood,” and some scholars link it to the god Maponos (“the divine son,” Welsh Mabon). No single translation is settled, so treat confident glosses with care.
Mispronunciations to avoid: “mab-in-OH-gee” with a soft “j” sound, “MAB-in-ogg,” and stressing the first syllable. Keep the g hard and the accent on OG, and you will sound at home.
Where it comes from: Middle Welsh, preserved chiefly in the White Book of Rhydderch and the Red Book of Hergest (14th century), though the tales themselves are older.
A memory trick: “mab-in-OG-ee” — lean on the OG in the middle, keep the g as hard as in “dog,” and finish on a bright “ee.”
These are the crown jewels of medieval Welsh storytelling. The Four Branches follow a linked cast — Pwyll and Rhiannon, the tragic Branwen, the shape-shifting magic of Math and Gwydion — through tales that blend the heroic, the comic and the uncanny. Alongside them, the wider collection Lady Charlotte Guest gathered under the title Mabinogion preserves some of the earliest Arthurian material in any language, including the great hunt of the boar Twrch Trwyth in Culhwch and Olwen.
The tales survive in two 14th-century manuscripts — the White Book of Rhydderch and the Red Book of Hergest — but their roots run deeper into oral tradition. Because their world sits alongside the Irish material yet stands quite apart from it, saying Mabinogi correctly is a good way to remember that “Celtic” is a family of distinct traditions, Welsh and Irish among them, not a single interchangeable one.
