Vnitního

Vnitního is a Czech grammatical form of the adjective vnitřní, meaning internal or inner. It is the masculine and neuter genitive singular form used when the noun it modifies is in the genitive case. For example: vnitřního prostoru, vnitřního orgánu, vnitřního svědomí. The nominative form is vnitřní.

Origin: from the root vnitř- meaning inside; related to the noun vnitro and to words in other Slavic languages with similar meaning. The -ní suffix marks adjectives.

Usage: common in technical or formal prose; can occur in anatomy, geography, philosophy, and psychology, as well as in everyday language when describing inner aspects or internal parts of something. It governs agreement with the noun it modifies in gender, number, and case, as with other Czech adjectives.

Orthography: standard Czech spelling uses diacritics; vnitřního is the correct form in formal writing. In texts without diacritics you may encounter nonstandard renderings such as vnitrniho, but these are typically avoided in proper Czech.
