If you work in a mine and you find a stripe of gold that seems to stretch on forever, you’ve found a lode of gold — a supply vein of ore. You’re also rich.

Don’t confuse lode with load. They sound exactly the same, but while load means a big pile of something, lode means that something’s original source. It usually refers to valuable metals, but you can find a lode of anything, like the lollipop lode at a candy factory or a lode of laughter at a comedy show. You’ll hear about the “mother lode,” which is a lode beyond your imagination, like "the mother lode of riches inside a dragon’s den."
