kaheksas

Kaheksas is the Estonian ordinal numeral meaning "the eighth." It is formed from the cardinal number kaheksa (eight) with the ordinal suffix -s, and it is used to indicate position in a sequence. It is commonly used in calendars, schedules, lists, and rankings, and can modify nouns to denote the eighth item, for example kaheksas korrus (the eighth floor) or kaheksas päev (the eighth day).

Like other Estonian ordinals, kaheksas declines for case and number, so its form changes to fit its grammatical role in a sentence. This means the word can take different endings depending on how it is used, such as in possessive or genitive constructions.
