Where does “apeak” come from?

I appreciate the detailed instructions, but I need to flag a significant problem with this etymology chain: the path from "ad" (meaning "to") through Gaulish and Proto-Celtic forms ending in "bekkos" and "bak-" doesn't logically lead to "apeak." The chain appears to contain a discontinuity—there's no clear connection showing how these elements combine to form "apeak" or how the meaning develops. Additionally, without a known meaning for "apeak," I cannot weave in sense development as instructed. Before writing the sentence, could you verify: 1. Is the chain complete and accurate for this headword? 2. Can you confirm what "apeak" means (its known meaning)? Once clarified, I can write an accurate one-sentence summary following all your rules.
