unverbrannte

Unverbrannte is a German adjective meaning not burned or not burnt. It is the feminine singular and plural inflection of unverbrannt when used attributively before feminine nouns or in plural. The base form unverbrannt is formed from the prefix un- together with verbrannt, the past participle of verbrennen (to burn). The adjective can also be used predicatively: Das Holz ist unverbrannt.

In usage, unverbrannt appears mainly in technical, scientific, culinary, or historical contexts to describe substances or states that have not undergone combustion or carbonization. It is commonly seen in discussions of combustion processes, fuels, or residues, where it contrasts with verbrannt or verbrannte, which describe burned or charred material. The word can function as a descriptive modifier in statements such as unverbrannte Teile remain after incomplete combustion, or the sample contains unverbrannte Bestandteile. The term is primarily used in German-language texts and tends to appear in formal or technical writing rather than everyday speech.

Related terms include verbrannt (burned), Verbrennung (combustion), and related vocabulary for burning and combustion. In historical or scientific discussions, unverbrannte states can be important for understanding efficiency, residue composition, and material behavior under heat.
