unverdaulicher

Unverdaulicher is the comparative form of the German adjective unverdaulich, meaning not digestible or not digestible by human enzymes. It is used to compare the digestibility of two substances, indicating that one is more indigestible than the other.

In nutrition and biology, unverdaulich describes components that cannot be broken down by human digestive processes, such as certain dietary fibers, lignin, or resistant starches. The expression der/unverdaulicher Anteil refers to the portion of a substance that remains undigested after digestion. In everyday language, unverdaulich or nicht verdaulich is often sufficient for general statements, while unverdaulicher is common when making direct comparisons.

Grammar and usage notes: as an attributive adjective before a noun, unverdaulich follows standard German declension rules. For example, ein unverdaulicher Anteil (indefinite article) and der unverdauliche Anteil (definite article) are typical forms in the respective cases. In predicative position, one would say Dieser Stoff ist unverdaulich, not unverdaulicher.

Relationship to related terms: unverdaulich is the base adjective meaning not digestible; unverdaulicher is its comparative. The term is mainly found in scientific, nutritional, and technical writing, where precise statements about relative digestibility are required. It is less common in casual speech, where simpler phrases such as nicht verdaulich or schwer verdaulich might be used.
