If you are learning Irish, the original language of Ireland, it's handy to know numbers 1-100. While it may sound daunting, we’re here to help. Read on for step-by-step instructions on counting to 100 in Irish, from 1-10, 11-19, and all the numbers between 20-100. You’ll also learn more about the 3 different ways you can count with numbers in the Irish-Gaelic language.

Counting in Irish to 100

  • Say the prefix "a" (“uh”) before each number from 1-10. For example, 1 = a haon (uh hayn), 2 = a dó (uh doh), and 3 = a trí (uh tree).
  • For 11-20, add the suffix "déag" to 1-9. For example, 11 = a haon déag (uh hayn dayg), 12 = a dó dhéag (uh doh yayg), and 13 = a trí déag (uh tree dayg).
  • Use this formula: [tens number] + a + [units number] for the 20s through the 90s. For example, 24 (fiche a ceathair) is [fiche (20)] + a + [ceathair (4)].

  1. Adding the “a” prefix slightly changes the pronunciation of the first letter of the word for the number. For example, the number one (haon) sounds like “uh hayn” with the prefix.[1]
    • 1 = a haon (uh hayn)
    • 2 = a dó (uh doh)
    • 3 = a trí (uh tree)
    • 4 = a ceathair (uh KyAH-hirzh)
    • 5 = a cúig (uh KOO-ig)
    • 6 = a sé (uh shay)
    • 7 = a seacht (uh shakht)
    • 8 = a hocht (uh hokht)
    • 9 = a naoi (uh nee)
    • 10 = a deich (uh djeh)

  1. For example, "a haon déag" means 11, and “a trí déag” means 13. The only exception is for the number 12. When a number ends in a vowel, like (2), the initial "d" sound of déag softens to "dh.” That means "a dó dhéag" is 12. Once you get to the number 20, it has its own word: “fiche.”[2]
    • 11 = a haon déag (uh hayn dayg)
    • 12 = a dó dhéag (uh doh YAY-og)
    • 13 = a trí déag (uh tree dayg)
    • 14 = a ceathair déag (uh KyAH-hirzh dayg)
    • 15 = a cúig déag (uh KOO-ig dayg)
    • 16 = a sé déag (uh shay dayg)
    • 17 = a seacht déag (uh shakht dayg)
    • 18 = a hocht déag (uh hokht dayg)
    • 19 = a naoi déag (uh nee dayg)

Ways to Count Irish Numbers

  1. 1
    Use standard counting to count items in a list. It adds the prefix "a,” and inserts an "-h-" for vowel-starting numbers. Standing counting allows numbers to be recited in a sequence, and is often used for mathematics or when stating a phone number. Here are some examples:[11]
    • a náid (zero)
    • a haon (one)
    • a dó (two)
  2. 2
    Count objects when the number modifies a noun. The grammar used affects both the number and the noun itself. When counting actual objects, the "a" prefix drops. The noun is always singular, though the first letter changes, based on the number:[12]
    • aon bhád amháin (one boat)
    • dhá bhád (two boats)
    • trí bhád (three boats)
  3. 3
    Use the 3rd counting system when counting people. This method uses a distinct set of "personal numbers" called “na huimhreacha pearsanta.” Here, different words are used for each number, and differ from the standard numbers. Some examples are ahead:[13]
    • Duine amháin (one person)
    • Beirt (two people)
    • Triúr (three people)

    Why is 12's format different than 11, 13, and all the other teens when counting to 100 in Irish?
    Community Answer
    Community Answer
    The Irish alphabet doesn't actually contain the letter H, the H you're seeing is the modern depiction of the "séimhiú" or lenition. It used to be depicted by a dot over the consonant, but more commonly now the letter "h" is used directly following the consonant. Its purpose is to make the word easier and more natural to say, basically. Saying "a dó déag" with the two harsh "d" sounds right after one another is a little awkward, so the séimhiú helps the speaker out by softening the second "d" sound into something that'll flow more naturally from the tongue. If you're interested in learning more, google séimhiú (lenition) and urú (eclipsis).
