4. a ceathair

5. a cúig

Examples of use:

• Counting to start a race: a haon, a dó, a trí.

• Serially numbered objects: seomra a seacht, bad a sé deag.

• Arithmetical work: a trí agus a naoi, sin é a dó dheag.

Giving quantities of some object, with the number preceding the noun:

aon bhó amháin, one cow

dhá bhó, two cows

trí bhó

ceithre bhó

cúig bhó

sé bhó

seacht mbó

ocht mbó

naoi mbó

deich mbó

aon bhó dhéag

dhá bhó dhéag

trí bhó dhéag

ceithre bhó dhéag

cúig bhó dhéag

sé bhó dhéag

seacht mbó dhéag

ocht mbó dhéag

naoi mbó dhéag

fiche bó

In this use, as you can see, aon, one, aspirates, "two" becomes "dhá" and aspirates, "four" has changed slightly, and from 11 on, there is a "dheag", similar to English "teen", added on. From 1 to 6, the number causes aspiration (where possible), and from 7 to 10, the number eclipses (where possible).

It all sounds complicated, but if you will practice on the lists above, and then try to use the numbers several times a day, say in counting or in reading license plates, one numeral at a time, you will be pleasantly surprised at your facility.

Now for a simpler and often-used help: telling time.

1. one o'clock -- Tá sé a haon a chlog

2. two o'clock -- Tá sé a dó a chlog

3. three o'clock -- Tá sé a trí a chlog

4. four o'clock -- Tá sé a ceathair a chlog

5. five o'clock -- Tá sé a cúig a chlog

6. six o'clock -- Tá sé a sé a chlog

7. seven o'clock -- Tá sé a seacht a chlog

8. eight o'clock -- Tá sé a hocht a chlog

9. nine o'clock -- Tá sé a naoi a chlog

10. ten o'clock -- Tá sé a deich a chlog
