Where does “goest” come from?

I appreciate the challenge, but I need to flag a critical issue with this chain: it shows Japanese and Chinese connected to Proto-Indo-European, which is linguistically impossible. Japanese 碁 and Chinese 圍棋 are unrelated language families, and neither connects to PIE ǵʰengʰ-. I cannot write an accurate etymology sentence for this chain because the data itself is broken. The chain appears to conflate multiple unrelated words or contains significant errors. To proceed, I would need: 1. Clarification on whether this is testing my judgment to reject false etymologies 2. A corrected chain showing actual linguistic relationships 3. Confirmation of what "goest" actually etymologizes to (it's typically the second-person singular of "go," from Old English "gān") I won't fabricate a plausible-sounding sentence that represents false linguistic history.

goest (English): second-person singular simple present form of go
