wejsciowych

Wejściowych is the genitive plural form of the Polish adjective wejściowy, meaning “input” or “entry” when describing a noun. In Polish, adjectives decline for gender, number, and case, which is why forms like wejściowych appear. The form wejściowych is used most often when the adjective modifies a noun in the genitive plural, for example in phrases describing multiple input items or in phrases in a larger sentence where the noun is in genitive: parametrów wejściowych, danych wejściowych.

Common compounds include dane wejściowe (input data), parametry wejściowe (input parameters), pliki wejściowe (input files), and strumienie wejściowe (input streams).

The term is widely used in computing, data processing, and information technology to distinguish input elements from output elements (wyjściowe). It can also appear in non-technical contexts where a general sense of "input" or "entry" is intended, but its usage is most frequent in technical terminology.

Etymology: from the noun wejście, meaning "entrance" or "input"; the adjective wejściowy forms follow standard Polish adjective declensions.
