Týdenn
Týdenn is not a standard entry in Czech lexicons; it most commonly appears as a typographical variant, stylized brand name, or online handle derived from the Czech word týden (meaning "week"). The form with a doubled final n is atypical in Czech orthography and does not correspond to a recognized grammatical form. Because of this, instances of týdenn are usually deliberate (branding, usernames) or accidental (typos, transcription errors).
Etymology and pronunciation: the base týden derives from Proto-Slavic and denotes a seven-day period. In Czech
Usage and contexts: týdenn may be used as a distinctive trademark or creative name for weekly publications,
