Expressing Uncertainty or Conditional Outcomes with the Subjunctive

Introduction

The subjunctive (el subjuntivo) is one of three moods in Spanish, and it is often used to talk about emotions.

You can find more on the differences between the subjunctive and the indicative here.

WEIRDO

Many of the verbs and phrases that require the subjunctive fit into the acronym WEIRDO: Wishes, Emotions, Impersonal expressions, Recommendations, Doubt/Denial, and Ojalá

Although this topic doesn't fit into our fancy acronym, it's still important to learn. Let's get started!

Conditional Outcomes

Overview

This type of sentence describes what will happen if another action is completed.

These actions are conditional upon another action being completed, so the subjunctive is used to convey a sense of uncertainty.

Many phrases with conditional circumstances have a connecting phrase or conjunctive expressions which introduce time limitations, conditions, concessions, or results.

As you can see below, the the key action (the one that must be completed for the second action to occur) is in the subjunctive.

Limpiaré el cuarto después de que salgan.
I will clean the room after they leave.
Me hablará tan pronto como llegue.
He will speak with me as soon as I arrive.
No iremos a la playa a menos que vayan también.
We won’t go to the beach unless they go as well.

Time Expressions

hasta que until
cuando when
luego que as soon as
después (de) que after
siempre que whenever

Let’s stay here until our friend arrives.
Cuando vea a sus padres los saludaré.
When I see your parents, I will tell them hello.

Conditions

These expressions introduce the idea of a condition, an action dependent on something else occurring.

Spanish English
dado que given that, since
a no ser que unless
en caso (de) que in case (that), if
a menos que unless
sea que whether, if
con/a condición de que on condition that
siempre y cuando que provided that, as long as
con tal (de) que provided that

I will leave whether they decide to go or not.

Concessions

These expressions introduce the idea of a concession, an action occurring despite something else.

Spanish English

aun cuando even if, even when
a pesar de que in spite of
por...que however

Even if you have nothing, you shouldn’t lose hope.
Por delicioso que sea, no quiero comerlo.
However delicious it may be, I don’t want to eat it.

Aunque and a pesar de que do not always take the subjunctive. If the conditional statement is considered hypothetical, you will use the subjunctive and if it is factual, you will use the indicative.

  • Aunque es un hombre difícil, sabe de negocios = Although he is a difficult man, he knows about business
