pravidelnými
Pravidelnými is a Czech grammatical term referring to the instrumental plural form of adjectives and nouns. In the Czech language, grammatical cases are used to indicate the function of a word within a sentence. The instrumental case, specifically in its plural form, is used to denote the means by which an action is performed, or to indicate accompaniment. For example, when describing something being done "with regular intervals," one would use the instrumental plural of the adjective "pravidelný" (regular), resulting in "pravidelnými." This form is applied to the adjective when it modifies a plural noun in the instrumental case. Understanding these declensions is crucial for correct Czech grammar. The ending "-ými" is a common marker for adjectives in the instrumental plural. Similarly, nouns will also take their appropriate instrumental plural endings when used in conjunction with "pravidelnými" adjectives, or when acting as the object of prepositional phrases that require the instrumental case. This grammatical feature allows for nuanced expression of relationships between words in a sentence.
