biologickému

Biologickému is the dative singular form of the Czech adjective biologický, which means biological or relating to biology and living organisms. It is used to describe a masculine or neuter noun in the dative case, such as in phrases conveying the indirect object or the recipient of an action.

In practice, biologickému occurs with masculine or neuter nouns in dative singular. For example, biologickému otci means “to the biological father,” and biologickému vzorku means “to the biological sample.” The feminine counterparts use a different ending, for example in the dative singular the feminine form is biologické. Adjectives in Czech must agree with the noun they modify in gender, number, and case, so the ending changes accordingly.

The form stems from the base adjective biologický, derived from the roots bio- (life) and -logický (related to study or logic, in this case biology). Czech adjectives are declined across seven cases, with distinct endings for masculine, feminine, and neuter genders and for singular and plural numbers. As a result, biologickému is specifically the masculine/neuter dative singular ending.

Biologický as a term is widely used in academic, scientific, medical, and everyday language to denote things pertaining to biology. While biologickému is a grammatical inflected form, its meaning remains tied to the same core sense of “biological,” describing relationships to biology or living organisms within the appropriate grammatical context.
