Do you know how to say that something "is necessary" in Spanish? Do you like telling people what "has to" be done? We'll teach you a simple formula!
To say something "is necessary" in Spanish, you might use the literal phrase es necesario (it's necessary) plus a verb's infinitive, or "to" form:
Es necesario usar papel, carbón o madera para encenderlo.
It's necessary to use paper, charcoal, or wood to light it.

And, to tell someone what they "have to" do, you could use verbs like tener que (to have to) or deber (must) plus the infinitive:
Tienes que mejorar esto.
You have to improve this.

However, if you are looking for a non-literal, conjugation-free alternative (to conjugate just the present indicative tense of tener que, for example, you have to memorize tengo que, tienes que, tiene que, tenemos que, tenéis que, and tienen que), we invite you to use the following, very simple formula, which can express the same thing as the previous three options in various contexts:
Hay que + infinitive
Don't get us wrong— you are going to have to learn those verb conjugations sooner or later! But, perhaps while you do, or as a viable alternative that native speakers often employ, you could opt for hay que + infinitive.
Hay comes from the Spanish verb haber, which is an auxiliary, or helping, verb that means "to have" or "to be" and appears in its conjugated forms as part of different verb tenses (e.g. the present perfect, pluperfect, etc.). Hay is haber's impersonal form, which never changes (it is always just hay in the present tense) and can mean "there is" or "there are." However, when hay is combined with que + infinitive, it becomes a fixed expression that means "it's necessary" (to do something). Let's see a couple of examples:
hay que darle la oportunidad de defenderse.
it's necessary to give him the opportunity to defend himself.

Note that the second example has been translated with "you have to," a more colloquial equivalent of "it's necessary" that includes the "universal you," implying "people" or "everyone." "One has to" or "one must" would also be valid translations.
The construction hay que + infinitive can be used in basically any context in which you want to say that "it's necessary" to do a particular thing. That said, we have included below a few scenarios in which you are likely to come across it. When reading the translations, keep in mind that while this impersonal construction has no specific subject, in cases in which the context or sentence makes clear who the speaker feels "has to" or "must" act in a particular way, the construction is often translated as if the subject were explicitly stated.
Since the construction hay que + infinitive explains what "people have to do," it only makes sense that it is often heard when talking about perceived wisdom about life:
En la vida hay que saber relajarse,
In life, you need to know how to relax,

As we mentioned earlier, you might use the expression hay que + infinitive to tell someone what to do without explicitly saying "you must," as in these two examples from the popular series Confidencial: Asesino al Volante:
Yo sé que les dijimos que no vinieran por acá pero hay que darles la buena noticia.
I know we told them not to come here, but we have to give them the good news.

In other cases, one might give a suggestion as to what they generally feel that "people" should do:
pues, hay que ir a México.
well, you have to go to Mexico.

Since giving directions entails explaining what "has to be done," you will often hear the construction hay que + infinitive in this context:
Después hay que torcer la primera calle a la izquierda.
Then you have to turn to the left on the first street.

Similarly, hay que + infinitive will often be heard in contexts where specific instructions are given, such as cooking a particular recipe or for some other process:
Hay que añadir el agua poco a poco y vamos amasando hasta obtener una mezcla homogénea.
It's necessary to add the water little by little and we start kneading until obtaining a homogeneous mixture.

These are, of course, just a few of the many situations in which you might use or encounter the construction hay que + infinitive.
While haber que + infinitive is probably most commonly seen the present indicative tense, it can also be found in other tenses. Let's see some examples in the imperfect tense , the preterite tense, and the future tense:
Definitivamente había que dejar el trabajo para dedicarme al restaurante.
I definitely had to leave my job to dedicate myself to the restaurant.

And remember that, just like for the present, you only have to remember one form of haber for each tense: había que for the imperfect, hubo que for the preterite, and habrá que in the future. Yabla's lesson entitled Había o habían muchos libros? elaborates further.
As you've probably surmised from our plethora of examples, the construction haber que + infinitive is extremely common and useful, and now that you're familiar with it: hay que practicarlo mucho (you have to practice it a lot)! And don't forget to leave us your suggestions and comments.
