Irish orthography—the system behind how Irish words are spelled—is a key part of understanding and mastering the Irish language. Whether you’re new to Gaeilge or brushing up on your skills, grasping the basics of Irish spelling and pronunciation can significantly improve your confidence and fluency.
At Gaeilgeoir AI, we help learners make sense of Irish orthography through intelligent, easy-to-use tools that demystify everything from broad and slender consonants to the infamous fada. In this post, we’ll break down how Irish spelling works, why it matters, and how our platform can support your journey toward fluency.
What Is Irish Orthography?
Irish orthography refers to the set of rules and conventions that govern how words are spelled and pronounced in the Irish language. Like many languages, Irish has a rich linguistic history—but its spelling rules can feel unfamiliar at first glance, especially to English speakers.
Words in Irish are deeply connected to their pronunciation, historical roots, and grammatical structure. This makes Irish orthography both beautiful and challenging.
Let’s start with why learning these spelling patterns is so essential for anyone hoping to speak or understand Irish with clarity.
Why Understanding Irish Spelling Matters
Many learners assume they can simply memorize vocabulary words without paying much attention to how they’re spelled—but in Irish, spelling is more than cosmetic. It tells you how to pronounce a word, what its grammatical role might be, and even its origin.
Here’s how Irish orthography helps learners:
- Improved Pronunciation – Spelling patterns show you whether a consonant is broad (leathan) or slender (caol), affecting pronunciation.
- Greater Reading Fluency – Recognizing standard patterns speeds up reading and comprehension.
- Easier Vocabulary Acquisition – Understanding root forms and suffixes helps you learn related words faster.
Key Features of Irish Orthography
Understanding the core elements of Irish spelling will help you decode and remember words more easily.
1. Broad and Slender Consonants
Consonants in Irish are pronounced differently depending on the surrounding vowels:
- Broad (leathan): Surrounded by a, o, or u
- Slender (caol): Surrounded by e or i
💡 Tip: There’s a common saying: caol le caol agus leathan le leathan—”slender with slender and broad with broad.” It helps you match vowels correctly around consonants.
2. The Fada (´)
The fada is an acute accent over a vowel (á, é, í, ó, ú). It changes the vowel’s sound and sometimes the meaning of the word.
- Seán (a name) vs. sean (old)
- bó (cow) vs. bo (not a word)

3. Silent Letters and Historical Spelling
Like English, Irish sometimes includes silent letters due to its historical roots. For example:
- bh can be pronounced like v or w, or remain silent.
- mh may sound like v, w, or be unpronounced in certain dialects.
This complexity is a challenge, but also part of what makes Irish so unique and culturally rich.
Pronunciation and Irish Orthography
One of the most common hurdles for learners is pronunciation. That’s where spelling becomes a powerful ally. With consistent rules—once you know them—Irish orthography can actually make it easier to predict how a word is said.
Here are a few examples:
- Sliabh (mountain) – Pronounced “shlee-uv”
- Oíche (night) – Pronounced “ee-ha”
- Gaeilge (Irish) – Pronounced “GWALE-guh”
The more you study these patterns, the more natural they become.
