Other forms: ideas

When you suddenly know what to do and a cartoon light bulb appears above your head, you've probably just had an idea. After burning the roast and dropping the mashed potatoes, ordering pizza seemed like your best idea all night.

Idea goes all the way back to idein in Greek, meaning “to see.” When someone says “Picture this!” they want to give you an idea. When you try to imagine something, idea can also mean a rough outline or a general sense: "This drawing I've made doesn't show every detail of my time machine, but it will give you some idea of how it works."
