ühekümnenda

Ühekümnenda is an Estonian word that translates to "tenth" in English when referring to ordinal numbers. It is the feminine form of the ordinal number "kümnes" (tenth). In Estonian grammar, adjectives and numerals agree in gender and number with the nouns they modify. Therefore, "ühekümnenda" would be used when referring to a feminine noun that is tenth in a sequence. For example, "ühekümnenda korrus" would mean "the tenth floor" if "korrus" (floor) were considered feminine in a specific context or grammatical construction, though "korrus" is typically treated as masculine or neuter in modern Estonian. More commonly, it would be used in phrases like "ühekümnenda osa" meaning "the tenth part" or "ühekümnenda lehekülje" meaning "of the tenth page."

The word is formed by combining the numeral "kümme" (ten) with the ordinal suffix "-s". The prefix "ühe-" is a common way to form ordinal numbers in Estonian, particularly for numbers ten and above, indicating a specific position within a set. While the masculine/neuter form is simply "kümnenda", the feminine form "ühekümnenda" explicitly marks the gender of the noun being described. Understanding these gender agreements is crucial for correct usage in Estonian.
