 How do you count in Irish?

Number one in Irish
In Irish (also known as Gaelic), the counting system is based on the number 20, rather than 10 as in English. Here's how to count in Irish:

  1. a haon
  2. a dó
  3. a trí
  4. a ceathair
  5. a cúig
  6. a sé
  7. a seacht
  8. a hocht
  9. a naoi
  10. a deich
  11. aon déag
  12. dó dhéag
  13. trí déag
  14. ceithre déag
  15. cúig déag
  16. sé déag
  17. seacht déag
  18. hocht déag
  19. naoi déag
  20. fiche

To count beyond 20, you would say the unit first (e.g. "two" for 2) and then add "ar fhiche" (which means "on twenty") before the unit. For example, to say 21 in Irish, you would say "dhá dheag ar fhiche" (two on twenty). For 22, it would be "dó dhéag ar fhiche" (two ten on twenty), and so on.
