English has a definite article ("the") and an indefinite article ("a" or "an").
Irish has only a definite article. In situations where "a" or "an" would be used in English, the noun is used with no article.
The definite article has two forms: an and na.
- an is used in front of singular nouns
- na is used in front of plural nouns (and feminine nouns in the genitive case).
