frekvennú

Frekvennú is a grammatical form used in Slovak, serving as the accusative feminine singular form of the adjective frekvenčný, which describes something related to frequency. It appears when a feminine noun in the direct object position is modified by a frequency-related attribute, for example frekvenčnú hodnotu signálu, meaning the frequency value of the signal.

The root frekven- comes from frekvencia (frequency), a term borrowed into Slovak from historical sources tracing back to Latin frequentia and related linguistic developments in the region. The adjective frekvenčný shares the same semantic field, indicating a property connected with frequency. In Slovak, adjectives agree with the noun they modify in gender, number, and case, so frekvenčnú occurs specifically with feminine nouns in the accusative singular.

In technical and scientific writing, frekvennú may appear in phrases that describe measured or specified frequencies, such as in signal processing, acoustics, or statistics. Its correct usage depends on the gender and case of the noun it modifies; misplacing the form can lead to grammatical awkwardness or misinterpretation of the measurement or property being described.
