Ready-Made Irish Combos
Three steps. Ten seconds.
Click the letters, or type on your own keyboard: on the Windows Irish layout, AltGr + a vowel gives á, é, í, ó or ú, and Shift makes it a capital.
Check the fadas and the mutations before you copy: fear or féar, i gCorcaigh with its small g and capital C.
Press Copy and paste into WhatsApp, email or a form: á, é, í, ó and ú arrive as themselves, not as plain vowels.
Irish copied here keeps every síneadh fada and every mutation.
Snapchat: caption an Oíche Shamhna or Bealtaine snap with the fadas and the h of lenition in place.
WhatsApp: send Nollaig shona daoibh or Breithlá sona duit to the family group, spelled the way the Caighdeán writes it.
Instagram: a bio that reads Gráinne or Ciarán, not the fada-less version that booking forms leave behind.
TikTok: caption a seisiún or a hurling clip from i gCorcaigh with the small g and the capital C.
Irish was printed in its own typeface for almost four hundred years. The first Gaelic type was cut in 1571 for a catechism commissioned by Elizabeth I. This cló Gaelach, with insular forms of letters such as r and s and a dot over a consonant to mark lenition (the ponc séimhithe), remained the normal type for Irish until the mid-20th century and was taught in schools until the 1960s. Modern spelling came from the new state: after 1922 every Act of the Oireachtas was translated into Irish, and the parliament’s translation service published a spelling handbook, Litriú na Gaeilge, in 1945, expanded it in 1947 and republished it in 1958 as An Caighdeán Oifigiúil, the Official Standard, which was updated again in 2017. In Roman type the dot became a following h, so the traditional alphabet of 18 letters (a b c d e f g h i l m n o p r s t u) and the síneadh fada on á é í ó ú now carry the whole language; j, k, q, v, w, x, y and z appear only in borrowed words. Irish is the national and first official language of Ireland and has been an official EU language since 1 January 2007, with full status since a translation derogation ended on 31 December 2021. The 2022 census counted 1,873,997 people who can speak Irish, but only 71,968 who speak it daily outside the education system.
In Irish the first letter of a word changes with the grammar. Lenition (séimhiú) adds an h after the first consonant and eclipsis (urú) writes another consonant in front of it, so “boat” appears as bád, bhád or mbád: a bhád is his boat, a bád her boat and a mbád their boat, and only the mutation tells them apart. After a preposition and the article, eclipsis is the rule: ar an mbóthar, on the road. The added letter stays lower case even before a capital, which is why place names read i gCorcaigh (in Cork) and i mBaile Átha Cliath (in Dublin), and why the people of Ireland are muintir na hÉireann. For search and spell-checking this means one word has several written shapes: a dictionary such as teanglann.ie has to send bhoird back to bord before it can find it.
Most Irish is typed on keyboards made for English. Ireland uses the UK-style QWERTY board, and Windows includes an Irish layout (KLID 00001809) that adds the fadas through AltGr: the right Alt key plus a vowel gives á, é, í, ó or ú, and AltGr with the apostrophe followed by a vowel works in programs that block the first method. Because the fada needs that extra key, it is often left out in chats, and many computer systems never accepted it. In 2018 University Hospital Galway told patient Ciarán Ó Cofaigh that its software could not store the fada in his name, and in 2019 the Data Protection Commissioner ruled that having a name spelled correctly in records was not an absolute right. In March 2026 Aer Lingus booking forms still rejected passenger names with a fada. The Official Languages (Amendment) Act 2021 now requires the IT systems public bodies use with the public to record a person’s name, address and title correctly in Irish, with the síneadh fada. A missing fada is not cosmetic: fear is a man and féar is grass, sean is old and Seán is a name. This keyboard gives á é í ó ú their own keys with capitals on Shift, so a message to the Gaeltacht areas of Galway, Mayo, Donegal, Kerry, Cork, Waterford and Meath keeps every mark.
Irish marks grammar at the start of a word: an added h, an added consonant, or a small letter before a capital.
The first letter of an Irish word changes with the grammar. Lenition adds an h, eclipsis adds a letter in front, and the word for “his”, “her” and “their” is the same a: only the mutation tells them apart.
When a name is eclipsed or takes a prefix, the added letter stays small and the capital stays put, so the capital lands in the middle of the word.
Standard Irish uses one mark, the síneadh fada, to show a long vowel. Leaving it out turns one word into another.
In the old Gaelic type, lenition was a dot written above the consonant, the ponc séimhithe. Roman type replaced the dot with a following h, and An Caighdeán Oifigiúil (1958) uses only the h.
