Where does “grandpa” come from?

I need to see the full etymology chain to write an accurate origin summary. You've provided: - English pa - Headword: grandpa (English) - Known meaning: (unknown) But the chain appears incomplete—it shows "English pa" without the older language stages that "grandpa" derives from. Could you provide the complete chain showing all languages from English back to the origin? For example, it should show something like: English grandpa ← [earlier language] gran/grand ← [another language] ... etc. Once I have the full chain with all intermediate language stages, I can write the accurate one-sentence summary.

grandpa (English): grandfather
