Viertens

Viertens is a German adverb used to introduce the fourth point in a sequence of arguments, items, or steps. It forms part of a conventional set of ordinal adverbs often used in formal writing and speeches: erstens, zweitens, drittens, viertens.

In contemporary usage, viertens appears mainly in written form such as essays, reports, and legal or academic texts. In everyday speech, speakers more commonly use phrases like "als viertes" or simply restructure the sentence to present the fourth point without the adverb. It is typically placed at the beginning of a clause or sentence and can be used with punctuation to separate enumerated items, for example: "Zuerst muss X geprüft werden; zweitens Y; viertens Z beachten."

Grammar and spelling notes: viertens is not a noun, but an adverb. It is written in lowercase unless it begins a sentence. It is closely related to other ordinal adverbs derived from the numbers, such as erstens, zweitens, drittens, fünftens, sechstens, and so on. The corresponding expressions can also appear as "als viertes" or "das vierte Argument" depending on style and context.

See also: erstens, zweitens, drittens, fünftens, sechstens. These forms are commonly taught in German grammar as part of organizing arguments and outlines in formal writing.
