Dinner
In short
The largest and most formal meal eaten during the day. In many Western cultures, it is typically served in the evening.
In plain words
Dinner is the main meal of your day. While some people eat it at midday, most people eat it after work or school in the evening.
A simple example
A family sitting down at 7:00 pm to eat a roast chicken with vegetables is having dinner.
Why it matters
It is often a social time for families or friends to gather. It provides the most significant amount of nutrition for many people.
Easy to mix up
It is often confused with supper, which is usually a lighter meal eaten later in the evening.
