Where does “basely” come from?

I notice the etymology chain provided shows "English base" repeated multiple times with Latin basis appearing once, but the chain structure is unclear and appears incomplete or corrupted. Additionally, the known meaning is listed as "unknown," which makes it impossible to weave in sense development as required. I cannot write an accurate one-sentence etymology for "basely" based on this chain, as doing so would violate the rule against inventing information. Could you provide: 1. A clarified etymology chain (the current one seems to have errors) 2. The actual meaning of "basely" (which is "in a base/dishonorable manner," but I should confirm this matches your source)
