Where does “bulkhead” come from?
I appreciate the detailed instructions, but I need to flag an issue: the chain provided traces "head" (hēafod → haubudą → kauput-/kapōlo), not "bulkhead." The word "bulkhead" is a compound where "bulk" (from Old Norse *bulki, a cargo heap) combines with "head." Following your rules strictly, I cannot write an accurate etymology for "bulkhead" using only this chain for "head," as that would be inventing an intermediate step or misrepresenting the compound's formation. Could you clarify: Should I write the etymology for "head" instead, or is there a different chain for "bulkhead" itself? If writing for "head," here's the sentence: Head comes from Middle English hede, from Old English hēafod, from Proto-Germanic haubudą, from Proto-Indo-European kauput
