from then on
Expresses that something applies or happens from a certain point in time onward and into the future. It is a more formal variant of 'von jetzt an' (from now on).
Fortan werden alle Sitzungen protokolliert.
From then on, minutes will be taken at all meetings.
The adverb 'fortan' is made up of 'fort' (onward, forward) and 'an'. It literally means 'onward from this point' and expresses a continuation into the future.
Die neuen Regeln gelten fortan für alle Mitarbeiter.
The new rules apply to all employees from now on.
'Fortan' often stands at the beginning of the sentence in position 1. In that case, the verb follows directly after it in position 2. It can also stand after the verb inside the sentence.
Fortan müssen Sie sich direkt an die Zentrale wenden.
From now on, you must contact headquarters directly.
This word belongs to written language or to a very formal, elevated style. It is rarely used in normal everyday conversation.
Der König erklärte, fortan werde das Volk keine Steuern mehr zahlen.
The king declared that from then on the people would no longer pay taxes.
so far
'bisher' and 'fortan' point in opposite directions in time. 'bisher' looks back and means: up to now, something has been this way. 'fortan' looks forward and means: from now on, or from a certain point in time onward, something applies in the future. The words can be confused because both have a point in time as a boundary. But with 'bisher', the period ends now; with 'fortan', it begins now. 'fortan' also sounds more formal than 'von jetzt an' (from now on).
