nízkej

Nízkej is a colloquial spelling of the Czech adjective nízký, meaning "low" or "short." It appears primarily in informal spoken Czech and in writing that imitates speech, such as dialogue in films, lyrics, or social media. In formal or standard Czech, the adjective before a masculine singular noun is nízký, not nízkej.

The form nízkej reflects how speakers often modify endings in rapid or casual speech. It is not considered standard grammar and is generally avoided in official or academic texts. It is much less common in feminine or neuter forms, where the standard nízká and nízké are used.

Nízkej can also appear as a surname or nickname in some contexts, though it is not a common Czech surname. When encountered as a proper name, it is typically treated as a stylistic or artistic choice rather than a canonical family name.

Etymologically, nízký derives from the Proto-Slavic root meaning "low," with cognates in other Slavic languages such as Polish niski and Russian nizkiy. The existence of nízkej as a variant illustrates how everyday speech patterns can influence orthography and informal usage beyond the standard language.
