Ordinal Numbers

Except for ordinals first, second and third all others are formed by adding -eamh / -amh to the cardinal number. The definite article is always used and must agree with gender and declension of noun. Examples are given for both masculine (cat (m) - cat) and feminine (cearc - hen) nouns
