Where does “bookcase” come from?

I appreciate the detailed constraints, but I need to flag an issue with this chain: it appears to have inconsistencies that make it impossible to write an accurate etymology following your rules. The chain jumps from "English case" to "Middle English booke" without showing how "bookcase" (a compound) derives from these separate elements. More critically, the chain lists the same form "Proto-Indo-European bʰeh₂ǵos" twice, and the sequence from Latin *casus* onward doesn't clearly connect to either "book" or "case" in a way I can verify. To write the required sentence accurately, I'd need: - A chain showing how "book" + "case" compound into "bookcase" - Clarification of which PIE roots lead to which modern words - Confirmation that intermediate steps aren't missing Could you verify the chain, or would you like me to attempt
