Where does “basic” come from?

I need to stop and flag an issue: this etymology chain appears to contain errors or formatting problems that make it impossible to write an accurate summary. The chain shows "English base" repeated multiple times with no progression to older languages, and includes contradictory elements (Latin basis appears in a chain of "English base" entries). There's also a gap where the chain should continue backward from Latin basis to its origin, but instead loops back to English. To write an accurate one-sentence origin summary, I would need: 1. A clear, logical chain showing actual language progression (e.g., English → Old English → Proto-Germanic → Proto-Indo-European, etc.) 2. Clarification of which forms are which language 3. The actual historical meanings at each stage 4. Confirmation that Latin *basis* is indeed the penultimate form before English adopted it Could you provide a corrected etymology chain for "basic"?
