zasadnicz
Zasadnicz is not a recognized standalone word in standard Polish. It does not appear in major dictionaries as an entry. Most often, zasadnicz is observed as a misspelling or truncated form of zasadniczy (fundamental, essential) or of zasadniczo (basically, essentially). The stem zasadnicz- exists in those words, but Polish orthography and morphology do not treat zasadnicz as an independent lemma. As such, occurrences of zasadnicz without a suffix are typically considered nonstandard or accidental.
In practice, zasadnicz may occur in nonstandard contexts such as creative writing, branding, or informal online
