presného

Presného is the genitive singular form of the Slovak adjective presný, meaning precise, exact, or accurate. It is used to modify masculine or neuter nouns in the genitive case, typically in contexts where precision is stressed. In standard Slovak, adjectives agree with the nouns they modify in gender, number, and case, so presného appears before masculine or neuter nouns in genitive singular.

Common uses include expressions of exactness in measurements, dates, times, quantities, and results. Examples: presného dátumu (the exact date), presného času (the exact time), presného odhadu (the exact estimate), presného výsledku (the exact result). The form also occurs with prepositions that require the genitive, for instance z presného dôvodu (for a precise reason).

For feminine nouns in the genitive singular, the corresponding form is presnej, as in presnej odpovede (the exact answer) or presnej metódy (the exact method). In plural forms, adjectives adopt the appropriate plural genitive endings.

In related languages, Czech uses a cognate form, such as přesného, which serves a similar grammatical role in genitive masculine/neuter. In Slovak, presného is a standard inflected form and does not stand alone as a separate lexical item outside its use as an adjective in genitive construction.

Overall, presného functions as a routine grammatical form to convey exactness in Slovak, appearing in formal, technical, and everyday contexts where precise specification is required.
