The Spanish verb decidir is a cognate of the English verb "to decide." It is an easy verb to learn because it can be used in the same contexts that you would use "to decide" in English. Also, decidir is a regular verb. When conjugating it you simply have to follow the pattern for other regular -ir verbs, such as recibir, escribir and vivir.

In this article you'll find the conjugations of decidir in the indicative mood (present, past, and future), the subjunctive mood (present and past), the imperative mood, and other verb forms like the gerund and past participle.

Using the Verb Decidir

When using the verb decidir, you will often talk about deciding to do something. Therefore, it should be followed by another verb. In English we would say "decide to do something." In Spanish, we say decidir hacer algo, so it is followed by the infinitive form of the verb. For example, Ana decidió ir a la fiesta (Ana decided to go to the party).

Decidir can also be followed by a noun, as in Tengo que decidir el tema de la fiesta (I have to decide the theme of the party), or it can be followed by an interrogative adverb, as in Ella debe decidir cómo hacer el trabajo (She must decide how to do the job), or Nosotros decidimos cuál camino tomar (We decide which way to go).

The verb decidir is sometimes used reflexively, decidirse. In that case, it has the meaning of "making up your mind." For example, Ana se decidió ir a la fiesta (Ana made up her mind to go to the party).

Present Progressive/Gerund Form

The gerund or present participle in Spanish, is the English -ing form, which can be used to form the present progressive and other progressive tenses. Be careful though, because in English you can use the present progressive to talk about future actions, as in Tomorrow she is deciding whom to invite, while in Spanish the present progressive can only refer to actions that are occurring in the present.

Present Progressive of Decidir está decidiendo Ella está decidiendo a quién invitar a la fiesta.  She is deciding whom to invite to the party.

Past Participle

The verb form called the past participle in Spanish has the ending -ado or -ido. The past participle is often used to form perfect tenses like the present perfect.

Present Perfect of Decidir ha decidido Ella ha decidido a quién invitar a la fiesta. She has decided whom to invite to the party.

Conditional Indicative

The conditional tense is used to talk about possibilities. It is the equivalent of the English form "would + verb."
