Ludwig's WRAP-UP
The phrase "that week onwards" is an effective linguistic tool for establishing a starting boundary in time. According to Ludwig AI, it is most at home in scientific and journalistic writing, where it serves to mark the onset of a continuous observation or policy. While it often functions as a shorthand for "from that week onwards", it remains grammatically correct on its own when the context clearly implies the origin. Writers should prioritize this phrase when they need to signal that a change is not merely an isolated event but the beginning of a persistent trend.
