Where does “humbug” come from?

I appreciate the task, but I need to flag a significant issue: the etymology chain provided doesn't actually connect to "humbug." The chain shows the development of "-er" and "-arius" suffixes, which would explain words like "hummer," but "humbug" is a distinct word with a different origin (likely from "hum" + "bug," or possibly from obsolete slang). I cannot write an accurate one-sentence summary because the chain doesn't support the headword "humbug." To proceed correctly, I would need: 1. The actual etymological chain for "humbug," or 2. Confirmation that the headword should be "hummer" instead Could you provide the correct etymology chain, or clarify which word this chain actually documents?
