njakému

Njakému is not a standing entry in standard Czech dictionaries. It most likely represents a non-diacritic variant of the Czech word nějakému, which is the dative singular masculine form of the indefinite adjective/pronoun nějaký, meaning some or any. The non-diacritic form commonly appears in texts where diacritics are omitted, such as basic ASCII renders, plain-text data, or certain OCR outputs. In everyday written Czech, the correct diacritic form is nějakému.

Etymology and morphology: The base form nějaký derives from the root jak (how) with the prefix n- and the universal indefinite meaning. As an adjective/pronoun, nějakký inflects for gender, number, and case; in the masculine singular dative it yields někomu? No, in this context the masculine singular dative is nějakému, which would modify a masculine noun in dative, for example nějakému muži (to some man). The diacritic-less njakému would be encountered only in non-standard or stripped texts.

Usage and normalization: In formal writing and standard orthography, the form with diacritics—nějakému—should be used. If you encounter njakému, it is typically a misspelling or a diacritics-stripped version of nějakému rather than a separate lexical item. There is no separate meaning or usage unique to njakému beyond the non-diacritic rendering of the standard form.
