henceforth
UK: ˌhensˈfɔːθ | US: ˌhensˈfɔːrθ
adv. from this time onward; starting now and continuing into the future
The word "henceforth" combines two Old English elements: "hence" (from "hennes," meaning "from here") and "forth" (meaning "forward"). Originally used in Middle English, it literally meant "from this point forward in time or place." Over time, it became a formal adverb emphasizing continuity from the present moment. The logic is straightforward: "hence" anchors the starting point, while "forth" projects the action forward, creating a temporal boundary.
Henceforth, all employees must submit reports by Friday.
The treaty declared that henceforth the borders would be closed.

Henceforth, the rules will be strictly enforced.
The king decreed that henceforth taxes would be reduced.
