podstatnom
Podstatnom is not a standard linguistic term in Czech, but a non-diacritic form that may appear in texts where diacritics are omitted. In such contexts it can be read as referring to related concepts in Czech grammar, most often in connection with the noun category or with the adjective podstatný. Because Czech relies on diacritics to distinguish words and forms, podstatnom is typically considered non-idiomatic and potentially ambiguous.
In standard Czech grammar, two related but separate ideas are podstatné jméno and podstatný. Podstatné jméno
For language processing and orthography, the distinction matters: podstatnom by itself is not a canonical lemma
