fußt

Fußt is the present tense form of the German verb fußen, used to mean that something is based on or rests on something else. It is most common in formal or written German and typically appears with a prepositional phrase introduced by auf, as in "Der Schluss fußt auf fehlerhaften Daten." In meaning, fußen is close to basieren, beruhen, or sich stützen auf, though it often carries a slightly more literary or elevated tone.

Etymology and usage. The verb fußen is derived metaphorically from the noun Fuß (foot), extending the idea of a foundation or footing to an argument, theory, or claim. Because of its formal feel, fußen appears more frequently in academic, legal, or analytical prose than in everyday conversation. When discussing a claim's foundation, speakers might choose alternatives such as basieren auf or beruhen auf depending on the desired nuance.

Conjugation and form notes. Fußen is a regular (weak) verb in German grammar. The present tense forms include ich fuße, du fußt, er fußt, wir fußen, ihr fußt, sie fußen. The past participle is typically gefußt and is used with perfect constructions (for example, "die These hat auf historischen Quellen gefußt"), though many writers also prefer paraphrastic alternatives like "basieren auf" in the past. The noun Fuß, meaning foot, is unrelated in meaning but shares the same root and is a separate word, always capitalized in German.
