Usage notes[edit]

  • May be used with nouns in both the singular and plural; the singular is more common in general, but the plural must be used with units of measurement and the like. Triggers lenition of nouns in the singular and no mutation of nouns in the plural:
  • cúig chatfive cats
  • cúig troithefive feet
  • cúig uairefive times
  • When used with the definite article, the definite article is always in the plural. When used with nouns modified by adjectives, the adjective is also in the plural and is always lenited after nouns in the singular; after nouns in the plural, the adjective only lenites after slender consonants:
  • cúig chapall bhánafive white horses
  • na cúig eaglais mhórathe five big churches
  • cúig capaill bhánafive white horses
  • na cúig eaglaisí mórathe five big churches
  • When referring to human beings, the personal form cúigear is used.
