IPA: /ˈloʊdˌstoʊn/
KK: /ˈloʊdstoʊn/
A type of stone that has magnetic properties and can attract iron; it is often used in navigation and as a natural magnet.
Sailors in ancient times used lodestones to help them find their way at sea.
Loadstone → The word is derived from "lode" (from Old English *lād*, meaning way or course) and "stone" (from Old English *stan*, meaning rock or stone). A loadstone is a stone that leads or guides, particularly in reference to its magnetic properties that direct towards the magnetic north.
Think of a 'way' or 'course' ('lode') that a 'stone' ('stone') can guide you, which helps you remember that a loadstone is a guiding stone.
