Where does “sideboard” come from?

I need to work with this etymology chain, but I notice it appears corrupted—it cycles through "English side | English backboard | English back" repeatedly without showing earlier language origins. A proper etymology sentence requires a chain that traces back through actual language stages (e.g., Old English → Proto-Germanic → Proto-Indo-European, or through Romance languages, etc.). The chain provided only shows English words at different periods without establishing their ultimate origin. I cannot accurately write the required sentence because: 1. The chain doesn't show progression to earlier languages 2. No original spellings from non-English languages are provided 3. No earliest/oldest meaning is supplied to explain sense development 4. The repeated cycling suggests data corruption **I'd need a corrected chain** showing sideboard's actual etymology (likely: English *sideboard* ← side + board, but tracing *side* back through Old English *sīde* and ultimately
