1. one

• Used independently; cannot be used before nouns without the further modifier amháin (“only”) (with which it is not required), the definite article, or a possessive determiner (when used by itself with nouns, it means "any"; see following section). Unlike 2–10 and 12, aon can be used to refer to people; the personal form aonar is largely confined in the meaning of “one person” to literary usage and is usually used idiomatically to mean “alone” or “single”. When used independently, it is always preceded by the particle a, which mutates it to haon:

• a haon, a dó, a trí... ― one, two, three...
• bus a haon ― bus number one
• a haon a chlog ― one o’clock

But:

• (aon) lá amháin ― one day
• aon chrann amháin/crann amháin ― one tree
• an t-aon duine ― the one person
• m'aon chara ― my one friend

• aonar
• aon déag
• aonú (ordinal)

• amháin
• duine (used as a pronoun to refer to human beings)
• ceann (used as a pronoun to refer to non-humans)
• céad (ordinal)
