"Over the last" and "over the past" are often used interchangeably, but there can be subtle differences in how they're perceived or applied. 1. "Over the last" This phrase tends to imply the most recent or final part of a time period that is still ongoing or just concluded. It often gives a sense of looking back at something specific or conclusive. - Example: "Over the last week, I’ve been working on this project." (Refers to the most recent week leading up to now.) 2. "Over the past" "Over the past" is more neutral and is used to describe a period that stretches backward from the present, often without focusing on the immediate end of that period. - Example: "Over the past week, I’ve learned a lot." (Similar meaning, but slightly broader, referring to any time within that week.) Subtle Difference: - "Over the last" often feels more specific to the immediate time before the present, as if marking the end of a series. - "Over the past" can feel more general, emphasizing the duration or span of time leading up to now without implying an end. In practice, though, they are used very similarly, and most people won't notice a big difference. The choice between them often comes down to personal preference or subtle context.
