   • 1906, E. C. Quiggin, “Áindrías an Ime”, in A Dialect of Donegal: Being the Speech of Meenawannia in the Parish of Glenties, page 196:

     Seachtmhain roimhe Shamhain chuaidh an Seónstanach siar ⁊ seacht ngearráin ⁊ péire cliabh air ghach gearrán fá choinne a chuid ime.

     A week before Samhain, Johnstone went back with seven geldings and a pair of panniers on each gelding for his butter.

• 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 eclipsis:

• seacht gcat ― seven cats
• seacht dtroithe ― seven feet
• seacht n-uaire ― seven 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 but only lenites after nouns in the plural when they end in slender consonants:

• seacht gcapall bhána ― seven white horses
• na seacht n-eaglais mhóra ― the seven big churches

But:

• seacht gcapaill bhána ― seven white horses
• na seacht n-eaglaisí móra ― the seven big churches

• When referring to human beings, the personal form mórsheisear (or seachtar) is used.

• seachtar (used with personal nouns)
• seachtú (ordinal)
