salt

The white, grainy stuff that makes food taste more flavorful is salt. You might sprinkle salt on your hot buttered popcorn to make it even more delicious.

Although many people eat too much salt, it's actually necessary for life, in both plants and animals. The scientific name for salt is sodium chloride, and it's been harvested from seawater and salt mines for most of human history. When you use salt as a verb, it means "shake salt onto." If someone's known as an old salt, it means they're an experienced sailor — and if they're the salt of the earth, they're honest and reliable.
