Where does “jitter” come from?

I appreciate the challenge, but I need to flag that this etymology chain appears corrupted or incomplete—it cycles through the same three terms without progressing to earlier languages or establishing etymological origins. To write an accurate one-sentence origin summary following your rules, I would need: 1. A chain that moves backward in time through actual source languages (e.g., English → Old English → Proto-Germanic, etc.) 2. Clarification of what "jitter" means (the chain provided shows "jit," "jitterbug," and "bug" but the headword is "jitter") 3. A known or reconstructed meaning from the earliest stage As written, I cannot responsibly generate a sentence claiming etymological origin when the data doesn't support one. Would you like to provide a corrected chain, or would you like me to demonstrate with a different word?
