A takeaway is food that's prepared for you to eat outside your home. It could be something simple like a sandwich or pizza.
When people talk about takeaways, they usually mean ordering food from a restaurant and having it delivered to their house or picked up on the way home from work. Sometimes it's because they're too tired to cook, sometimes they just don't feel like cooking, and other times they want a special treat. Takeaways are really popular in big cities where you can get all sorts of food from different countries delivered right to your doorstep.
The word "takeaway" is often used in British English - if you hear someone say it, that's what they mean! If you're not sure what kind of food it will be or how much money it costs, don't worry, the restaurant will usually tell you on the phone.
A restaurant that sells food to be eaten elsewhere.
Example: If you're hungry, there's a takeaway just around the corner.
(Of food) intended to be eaten off the premises from which it was bought.
