How to Use “Hacer falta que” in Spanish with the Subjunctive

Introduction

One of the most useful expressions in Spanish is hacer falta que, which translates to need that or it is necessary that in English. This impersonal construction is essential for expressing necessity and requirement in Spanish, and it always requires the subjunctive mood in the dependent clause. Understanding how to use hacer falta que with the subjunctive will significantly improve your ability to communicate needs, obligations, and requirements in Spanish. Whether you are a beginner or intermediate learner, mastering this grammar structure will help you express yourself more naturally and accurately in both spoken and written Spanish.

What Does Hacer Falta Que Mean?

The expression hacer falta que is an impersonal construction that conveys the idea of necessity, requirement, or need. When you use hacer falta que, you are expressing that something is necessary or required for something else to happen. The phrase literally breaks down as hacer (to make or do), falta (lack or necessity), and que (that), creating a structure that functions similarly to English phrases like it is necessary that or we need that.

In Spanish, hacer falta que is commonly used in everyday conversation and formal writing. It is more natural and frequently used than the English equivalent phrases in many contexts. The expression emphasizes necessity from an objective standpoint, rather than from a personal desire or preference. This distinction is important because it influences both the structure and the mood of the verb that follows.

The Subjunctive Mood: A Brief Overview

Before diving deeper into hacer falta que, it is essential to understand the subjunctive mood. The subjunctive is one of the three main moods in Spanish, alongside the indicative and the conditional. While the indicative mood expresses facts and certainties, the subjunctive expresses doubts, desires, requirements, possibilities, and hypothetical situations. It is used when there is an element of uncertainty, subjectivity, or an expression of necessity or obligation.

The subjunctive mood in Spanish is triggered by specific verbs and expressions, and hacer falta que is one of them. Whenever you use hacer falta que, the verb in the dependent clause must be in the subjunctive form. This is a grammatical requirement, not an optional choice. Understanding this connection will help you use the expression correctly.

Structure and Conjugation of Hacer Falta Que

The structure of hacer falta que follows a specific pattern. The expression begins with the impersonal form hacer in the third person singular or plural, depending on the context. The most common form is hace falta que, meaning it is necessary that or there is a need that. However, you will also encounter other conjugations such as hacía falta que (it was necessary that), hará falta que (it will be necessary that), and haría falta que (it would be necessary that).

Let us examine the different tenses of hacer falta que:

Present: Hace falta que (it is necessary that)
Past: Hacía falta que (it was necessary that)
Future: Hará falta que (it will be necessary that)
Conditional: Haría falta que (it would be necessary that)

Each of these forms requires the subjunctive mood in the verb that follows. The subjunctive form you choose depends on the tense expressed in the hacer falta que clause. Generally, if hace falta que is in the present, you will use the present subjunctive. If it is in the past or conditional, you will often use the imperfect subjunctive.

Using Present Subjunctive with Hacer Falta Que

The most common and frequently used form of hacer falta que is with the present subjunctive. This combination expresses current necessity or immediate requirements. To use the present subjunctive correctly with hace falta que, you must understand how to conjugate verbs in the present subjunctive form.

For regular verbs, the present subjunctive is formed by taking the yo form of the present indicative, removing the o, and adding the subjunctive endings. For -ar verbs, the endings are -e, -es, -e, -emos, -éis, -en. For -er and -ir verbs, the endings are -a, -as, -a, -amos, -áis, -an.

Here are some practical examples:

Hace falta que estudies para el examen.
(It is necessary that you study for the exam.)

Hace falta que nosotros terminemos el proyecto hoy.
(It is necessary that we finish the project today.)

Hace falta que ellos lleguen a tiempo para la reunión.
(It is necessary that they arrive on time for the meeting.)

In each of these examples, the verb following hace falta que is in the present subjunctive form. Notice how the expression conveys necessity and obligation, and the subjunctive mood is required to express this grammatical relationship.

Using Imperfect Subjunctive with Hacer Falta Que

The imperfect subjunctive is used with hacer falta que when the main clause is in a past tense or when expressing hypothetical situations. The imperfect subjunctive has two possible forms in Spanish, often called the -ra form and the -se form. Both are equally correct, though the -ra form is more commonly used in modern Spanish.

To form the imperfect subjunctive, take the third person plural form of the preterite, remove the -ron ending, and add either -ra, -ras, -ra, -ramos, -rais, -ran or -se, -ses, -se, -semos, -seis, -sen.

Here are examples using the imperfect subjunctive:

Hacía falta que estudiaras más para aprobar el examen.
(It was necessary that you study more to pass the exam.)

Haría falta que nosotros trabajáramos juntos en este proyecto.
(It would be necessary that we work together on this project.)

Hacía falta que ella llegara más temprano cada día.
(It was necessary that she arrive earlier each day.)

Notice how these examples express past necessity or hypothetical requirements. The imperfect subjunctive with hacer falta que creates a more distant or conditional sense of necessity.

Irregular Verbs and Hacer Falta Que

Many commonly used verbs in Spanish are irregular in the subjunctive mood, and these irregularities must be remembered and applied when using them with hacer falta que. Irregular verbs in the subjunctive often follow predictable patterns, but they do not follow the regular conjugation rules.

Some of the most common irregular subjunctive verbs include:

Ser: sea, seas, sea, seamos, seáis, sean
Estar: esté, estés, esté, estemos, estéis, estén
Ir: vaya, vayas, vaya, vayamos, vayáis, vayan
Haber: haya, hayas, haya, hayamos, hayáis, hayan

When using these irregular verbs with hacer falta que, you must apply the correct irregular subjunctive form. For example:

(It is necessary that you be honest in your answers.)
