Grocery
Now I'll teach you some signs for shopping. Shop, grocery shopping, grocery store. You can see the difference between shopping and store. Store is a noun, shopping is an action. When you're in the store, you might be in a grocery store and you might see a cashier, cashier. Aisles, aisles; fruit, meat, cereal, bread, milk -- you might have the dairy aisle. So we'll review -- shopping, store, cashier, aisle. Practice those signs.
