porednikom

Porednikom is the instrumental singular form of the noun porednik, a grammatical term used in some South Slavic language grammars to denote a coordinating conjunction, or the broader class of coordinating words that link elements of equal syntactic status. A coordinating conjunction, or porednik, connects words, phrases, or clauses that could stand alone, forming coordinate structures. Typical coordinating conjunctions express addition (and), choice (or), contrast (but), or cause and result (for). In many linguistic traditions, coordinating conjunctions are grouped under the category of porednik and are distinguished from subordinating conjunctions, which introduce dependent clauses.

In the descriptive grammars of languages such as Croatian, Serbian, and Bosnian, poredniks behave similarly to their English equivalents like and, or, and but. They can appear between elements in a sentence and may interact with punctuation rules, such as comma placement in enumerations or compound structures, depending on the language.

The word porednik itself is declined in languages with case systems, and its instrumental singular form is porednikom. This form is used when the word functions as a noun within a sentence that requires the instrumental case, or when describing the word in a grammatical analysis. For example, a grammar reference might note that the porednik coordinates noun phrases, with porednikom appearing in instructional text when the noun is discussed in instrumental form.
