Kiekvienu

Kiekvienu is the instrumental singular form of the Lithuanian determiner or adjective kiekvienas, meaning “every” or “each.” It is used to express “with every” or “in every” when describing manner, means, or extent, and appears with masculine or neuter nouns in instrumental usage.

The form is part of the standard Lithuanian declension of the determiner and follows the same grammatical rules as other adjectives when coordinating with a noun in the instrumental case. It is not used as a stand-alone pronoun; rather, it modifies a noun within a phrase such as in instrumental contexts.

Common uses include fixed expressions where the instrumental conveys a sense of comprehensiveness or repetition, such as in phrases meaning “in every case” or “with every step.” Its presence signals that the statement applies across all instances of the referenced noun.

Etymology traces kiekvienu to the base term kiekvienas, with the instrumental ending -u following Lithuanian pattern for masculine and neuter singular adjectives in instrumental form. This mirrors related adjectives that form instrumental endings in a similar way.

Examples of usage are typical in formal and written Lithuanian: “Kiekvienu atveju reikia patikrinti duomenis.” This demonstrates how the instrumental form operates within a sentence to convey universality.
