pharaoh

The word comes from Egyptian pr-ꜥꜣ, literally "great house," combining pr ("house") and ꜥꜣ ("great, big"). It passed through Biblical Hebrew Parʿō, Koine Greek Pharaṓ, Late Latin Pharaō, and Old English Pharao before reaching Middle English as pharao, pharaon, farao, or faraon.

What began as a term for the royal palace itself shifted to refer to the ruler who lived inside it, and that meaning is the one that survived into English.

The facts given don't establish any English cognate connected through this word's history.
