Tételként

Tételként is a Hungarian adverb formed from the noun tétel (theorem) with the suffix -ként, meaning “as a theorem” or “in the form of a theorem.” In mathematical and logical writing, tételként is used to indicate that a claim is being presented as a formal, provable result rather than as an informal remark or a lower-status statement.

The expression serves to mark the rhetorical status of a proposition within an argument. A statement labeled tételként is typically treated as a central result that will be proven, and it often accompanies or precedes a full proof. This labeling helps readers distinguish major results from lemmas, corollaries, or auxiliary observations. While many authors simply state a theorem without the adverb, tételként appears in expository or meta-text to emphasize the result’s role in the overall structure of the proof.

Usage and style notes: tételként is most common in formal writing, lecture notes, or scholarly articles where the author wants to foreground a claim as a theorem. It is less common to see the adverb used in everyday mathematical discourse; in most cases the result is presented directly as a theorem (tétel) or as a claimed statement (állítás) that will be proven.

Examples: “A fenti állítást tételként bebizonyítjuk.” “Legyen X adott, és tételként fogom bebizonyítani, hogy …” These illustrate how the adverb anchors the claim within the theorem-proof framework.
