“Mettersi a” in Italian

“Mettersi a” Meaning

Mettersi a is an Italian construction used to express the idea of starting or beginning an action, often with a sense of spontaneity or casualness.

Linguistically speaking, it is composed of:

  • Mettersi: a reflexive verb, meaning it requires a reflexive pronoun. The fact that it makes use of a reflexive verb shows that the action is being done by and directed back toward the subject
  • A: this preposition follows mettersi and connects it to a present infinitive verb, indicating what action the subject is beginning.

This structure gives a sense of starting something spontaneously or without much planning, which differs from the straightforward iniziare a or cominciare a (both meaning “to begin”, “to start).

How to use “Mettersi a” in Italian

In Italian, mettersi a is used flexibly across various verb tenses. However, no matter the tense mettersi is conjugated in, it is always followed by a present infinitive verb.

For instance:

Fra poco mi metto a studiare.

In a bit I’ll start studying.

Mi sono messo a studiare alle 3.

I started studyingat 3.

Mi metterò a studiare dopo.

I will start studying later.

In all cases, studiare is kept in the infinitive form.
