kaheksakümnes
kaheksakümnes is the Estonian word for "eightieth". It is an ordinal numeral, indicating position in a sequence. In Estonian, the cardinal number for eighty is "kaheksakümmend". The ordinal form is created by adding the appropriate ending, which in this case is "-s" for the nominative singular. Therefore, "kaheksakümnes" signifies the position of eighty in a list or a series. It would be used in contexts such as referring to the "eightieth birthday" (kaheksakümnes sünnipäev) or the "eightieth chapter" (kaheksakümnes peatükk). The word follows typical Estonian grammatical rules for forming ordinal numbers. Like other ordinal numerals, it can be declined to agree with the noun it modifies in terms of case, number, and gender, although Estonian does not have grammatical gender. Understanding "kaheksakümnes" is essential for comprehending ordinal relationships within the Estonian language.
