Where does “cakewalk” come from?

I appreciate the detailed rules, but I need to flag a significant problem with this etymology chain before writing the summary. The chain provided has issues that make it impossible to write an accurate sentence: 1. **Circularity**: "Old Norse kaka" appears twice consecutively with no progression 2. **Proto-Indo-European gog** appears twice with no change 3. **Logical gap**: The chain jumps from "Old Norse kaka" to "Proto-Indo-European gog" to "Proto-Indo-European wel-" without clear connection to how these relate to English "cakewalk" 4. **Missing information**: No meanings are supplied for any term, so I cannot "weave in the oldest one to explain the sense development" as instructed 5. **Unclear path**: It's unclear whether this chain is meant to show: kaka→gog→wel, or separate branches, or something else
