Common phrasal verbs using the verb eat

Let us begin with some practical phrasal verbs that English speakers use regularly.

Eat in

Examples:

• I’m not feeling very well, so could we eat in tonight instead of going out?
• We’ve been spending too much money lately, so we’re trying to eat in more often.

This is a very common phrasal verb in everyday English, especially when discussing plans.

Eat out

Meaning: to eat in a restaurant, café, or somewhere away from home.

Examples:

• I don’t feel like cooking. Shall we eat out tonight?

Eat in and eat out are useful opposites, so they are worth learning together.

This expression is often used by parents, teachers, or anyone encouraging someone to finish their food.
