seither

Seither is an English adverb meaning since that time; from that moment onward. In modern English it is considered archaic or literary and is rarely used outside of historical writing, translations, or quotations from older sources.

Etymology: The form is ultimately cognate with the German seither, which also means since then. English borrowed the term through translations and literary usage, especially in the early modern period. In English, seither has largely fallen out of everyday use and is encountered mainly in historical texts or in attempts to reproduce older diction.

Usage: In contemporary writing, seither is uncommon and often marked as archaic. It tends to appear in quotations, scholarly works dealing with historical language, or stylistic reproductions of older prose. For ordinary prose, since then, ever since, or from that time onward are preferred and clearer to modern readers. When used, it signals a formal or antiquated register.

Examples: There have been no changes seither. Since that event, seither, the city has prospered. In modern editing, these would typically be rewritten as “There have been no changes since then” or “Ever since that event, the city has prospered.” Readers should expect seither mainly in translated texts, period pieces, or discussions of language history, rather than in everyday usage.
