Irish orthography has evolved over many centuries, since Old Irish was first written down in the Latin alphabet in about the sixth century AD. Prior to that, Primitive Irish was written in Ogham. Irish spelling is mainly based on etymological considerations, very much like English orthography, although a spelling reform in the mid-20th century simplified the relationship between spelling and pronunciation somewhat.

There are three dialects of spoken Irish: Ulster (now predominantly in County Donegal), Connacht (Counties Mayo and Galway), and Munster (Counties Kerry, Cork, and Waterford). Some spelling conventions are common to all the dialects, while others vary from dialect to dialect. In addition, individual words may have in any given dialect a pronunciation that is not reflected by the spelling (rather like the English word colonel, whose spelling denotes its pronunciation quite poorly).

The alphabet

A sample of Gaelic script.

Prior to the 20th century Irish was usually written using the uncial Gaelic script. The uncial alphabet, together with letter name pronunciations and lenited letters is shown below.

Use of the uncial script is today almost entirely restricted to decorative and/or self-consciously traditional contexts. The dot above the lenited letter is usually substituted with a following h in the standard Roman alphabet. The only other use of h Irish is for vowel-initial words after certain proclitics (e.g. go hÉireann 'to Ireland) and for words of foreign derivation such as hata 'hat'.

The alphabet now used for writing the Irish language consists of the following letters, written in antiqua:

a á b c d e é f g h i í l m n o ó p r s t u ú;

Modern loanwords also make use of j k q v w x y z. Of these, j and v are the most common. The letters' names are spelt out thus:

á bé cé dé é eif gé héis í eil eim ein ó pé ear eas té ú

along with jé cá cú vé wae eacs yé zae.

Tree names were once popularly used to name the letters. Tradition taught that they all derived from the names of the Ogham letters, though it is now known that only some of the earliest Ogham letters were named for trees.

ailm (white fir), beith (birch), coll (hazel), dair (oak), edad/eabhadh (poplar), fern/fearn (alder), gath/gort (ivy), uath (hawthorn), idad/íodhadh (yew), luis (rowan), muin (vine), nin/nion (ash), onn (gorse), peith (dwarf alder), ruis (holander), sail (willow), tinne/teithne (holly), úr (heather)

Although the uncial script remained common until the mid-20th century, efforts to introduce antiqua began much earlier. Theobald Stapleton's 1639 catechism was printed in antiqua, and also introduced simplified spellings such as suí for suidhe and uafás for uathbhás, though these did not become standard for another 300 years.

Consonants

The consonant letters generally correspond to the consonant phonemes as shown in this table. See Irish phonology for an explanation of the symbols used and Irish initial mutations for an explanation of eclipsis. In most cases, consonants are 'broad' (velarized) when the nearest vowel letter is one of a, o, u and 'slender' (palatalized) when the nearest vowel letter is one of e, i.

Observations

• When e, é, i, or í come after or before a consonant, they make the consonant slender.
• Between a consonant and a vowel, or vice-versa, e and i are usually silent, and just indicate that the adjacent consonants are slender. However, they may be pronounced in the digraphs ei, ia, io, oi, ui.
• The accented letters é and í are always pronounced.
• In digraphs and trigraphs containing a vowel with an acute accent (known in Irish as a fada or síneadh fada), only the accented vowel is normally pronounced.

The epenthetic vowel

In a sequence of short vowel + /l, r, n/ + labial or velar consonant an unwritten /ə/ gets pronounced between the /l, r, n/ and the following consonant:

• gorm /ˈgɔɾˠəmˠ/ 'blue'
• dearg /ˈdʲaɾˠəg/ 'red'
• dorcha /ˈd̪ˠɔɾˠəxə/ 'dark'
• ainm /ˈanʲəmʲ/ 'name'
• seanchaí /ˈʃan̪ˠəxiː/ 'storyteller'
• leanbh /ˈlʲan̪ˠəw/ 'child'
• colm /ˈkɔɫ̪əm/ 'dove'

There is no epenthesis before voiceless stops or after long vowels and diphthongs:

• corp /kɔɾˠpˠ/ 'body'
• olc /ɔɫ̪k/ 'bad'
• téarma /tʲeːɾˠmˠə/ 'term'
• dualgas /ˈd̪ˠuəɫ̪gəsˠ/ 'duty'

Special pronunciations in verb forms

In verb forms some letters and letter combinations are pronounced differently from elsewhere.

In the imperfect, conditional, and imperative, -dh is pronounced /tʲ/ before a pronoun beginning with s-:

• mholadh sé /ˈwɔɫ̪ətʲ ʃeː/ 'he used to praise'
• bheannódh sibh /ˈvʲan̪ˠoːtʲ ʃɪvʲ/ 'you (pl.) would bless'
• osclaíodh sí /ˈɔsˠkɫ̪iːtʲ ʃiː/ 'let her open'

Otherwise it is pronounced /x/:

• mholadh an buachaill /ˈwɔɫ̪əx ə ˈbˠuəxəlʲ/ 'the boy used to praise'
• bheannódh na cailíní /ˈvʲanoːx n̪ˠə ˈkalʲiːnʲiː/ 'the girls would bless'
• osclaíodh Siobhán /ˈɔsˠkɫ̪iːx ˈʃʊwaːn̪ˠ/ 'let Siobhán open'

In the preterite impersonal, -dh is pronounced /w/:

• moladh é /ˈmˠɔɫ̪əw eː/ 'he was praised'
• beannaíodh na cailíní /ˈbʲan̪iːw nə ˈkalʲiːnʲiː/ 'the girls were blessed'

-(a)idh and -(a)igh are pronounced /ə/ before a pronoun, otherwise /iː/:

• molfaidh mé /ˈmˠɔɫ̪hə mʲeː/ 'I will praise'
• molfaidh Seán /ˈmˠɔɫ̪hiː ʃaːn/ 'Seán will praise'
• bheannaigh mé /ˈvʲan̪ˠə mʲeː/ 'I blessed'
• bheannaigh Seán /ˈvʲan̪ˠiː ʃaːn/ 'Seán blessed'

In the future and conditional, f (broad or slender) has the following effects:

1. After vowels and sonorants (/ɫ̪ lʲ mˠ mʲ n̪ˠ nʲ ɾˠ ɾʲ/) it is pronounced /h/:
   • molfaidh /ˈmˠɔɫ̪hiː/ 'will praise'
   • dhófadh /ˈɣoːhəx/ 'would burn'
   • déarfaidh /ˈdʲeːɾˠhiː/ 'will say'
2. It makes a voiced obstruent (/bˠ bʲ vʲ d̪ˠ g/) or /w/ voiceless:
   • scuabfadh /ˈsˠkuəpəx/ 'would sweep'
   • goidfidh /ˈgɛtʲiː/ 'will steal'
   • leagfadh /ˈlʲakəx/ 'would lay'
   • scríobhfaidh /ˈʃcɾʲiːfˠiː/ 'will write'
   • shnámhfadh /ˈhn̪ˠaːfˠəx/ 'would swim'
3. It is silent after a voicless obstruent (/k c x ç pˠ pʲ sˠ ʃ t̪ˠ tʲ/)
   • brisfidh /ˈbʲɾʲɪʃiː/ 'will break'
   • ghlacfadh /ˈɣɫ̪akəx/ 'would accept'
4. But in the future and conditional impersonal f is often /fˠ, fʲ/
   • molfar /ˈmˠɔɫ̪fˠəɾˠ/ 'one will praise'
   • dhófaí /ˈɣoːfˠiː/ 'one would burn'
   • scuabfar /ˈsˠkuəbˠfˠəɾˠ/ 'one will sweep'
   • brisfear /ˈbʲɾʲɪʃfʲəɾˠ/ 'one will break'
5. In the past participle th (also t after d) is silent but makes a voiced obstruent voiceless:
   • scuabtha /ˈsˠkuəpˠə/ 'swept'
   • troidte /ˈt̪ˠɾˠɛtʲə/ 'fought'
   • ruaigthe /ˈɾˠuəcə/ 'chased'
