overlapping
UK: ˌəʊvəˈlæpɪŋ | US: ˌoʊvərˈlæpɪŋ
adj. covering part of the same area or time as something else
v. (present participle) to cover part of the same area or time as something else
The word "overlap" combines "over" (from Old English "ofer," meaning "above" or "across") and "lap" (from Old English "læppa," meaning "fold" or "loose part of a garment"). Originally, "lap" referred to the loose fabric that could be folded over another layer, and "overlap" evolved to describe the partial covering of one thing by another. The "-ing" suffix forms the present participle, indicating an ongoing action or state.
