In this Spanish conjugation lesson we will learn how to conjugate the verb acostumbrar in the Futuro Perfecto tense of the Indicativo mood. It means we will see step by step how to create and translate forms of each grammatical person.

How to translate Futuro Perfecto to English

Note that the phrases in English provided below next to each conjugation are not direct translations from Spanish to English. They are usually the closest general equivalents. The example differences are:
  • In Spanish conjugation, there is the form usted in the third person singular. But this person does not translate to the English third person singular. It translates to the so called formal you and uses the inflected form which is most often represented as he/she/it in English conjugation charts.
  • Similar situation happens in the third person plural, where ustedes translates to the English plural formal you but uses the form which corresponds to the they form in English.
  • Tenses are used differently in Spanish and English, so the actual translation should always take into account the context and focus on translating the meaning, not just words.
  • In both languages each verb may have multiple meanings and not every meaning translates directly to the other language. Here also, the context and focusing on the particular meaning helps to create the most accurate translation.


Step by step instructions

Futuro Perfecto is a compound tense (Spanish: compuesto). It means that all of its conjugated forms consist of two words. In Spanish language, there are also simple tenses, where each conjugated verb form is one word long.

In a compound tense the endings of the auxiliary verb change, not the endings of the main verb, which is the case in Spanish simple tenses.In the compound tenses, every person’s form consist of two parts:
  • A conjugated form of the auxiliary verb haber. In case of the Futuro Perfecto de Indicativo tense, we use the Futuro Imperfecto de Indicativo (Future) conjugation of haber
  • Past Participle, which is always the same in every compound tense for a given verb
Check out the conjugation charts and this haber conjugation lesson to learn how to conjugate the auxiliary verb haber. That’s a separate topic, so for brevity we’ll focus on the parts derived from acostumbrar only in this lesson.In order to create the Participio form, we need a stem and an ending. We use the stem of the infinitive of the main verb, and a single ending, which depends on the conjugation group of the main verb. So we start by splitting the infinitive into a stem and an ending. It’s really easy to do – simply remove two letters from the end of the infinitive and you have the ending – one of -ar, -er, -ir. What’s left is the stem.So for our verb:
  • the stem is: acostumbr-
  • and the ending is: -ar
Based on the ending of the infinitive we can tell that acostumbrar belongs to the -ar verb group. This group, in turn, uses the -ado ending in its Participio form. Putting all that together, our Participio is: acostumbrado.

Now, as we understand how both parts used by this tense are created separately, we can move on with creating the final conjugation forms.
In order to create the first person singular form, we simply take the first person singular form of haber conjugated in Futuro Imperfecto de Indicativo, which is habré. To that we add the Participio acostumbrado to get habré acostumbrado:
  • yo habré acostumbrado – I will have accustomed
Next, to create the form for the second person singular, we again need to take the second person singular form of haber from the Futuro Imperfecto de Indicativo tense, and it is habrás. To this auxiliary verb we add the Participio acostumbrado (so the exact same word as previously) to get habrás acostumbrado:
  • tú habrás acostumbrado – you will have accustomed
Similarly, if we want to create the form for the third person singular, we conjugate haber in the Futuro tense and we utilize the corresponding person’s form (third person singular), namely habrá. Then we also take the same Participio as for all other persons, and putting them together we get habrá acostumbrado:
  • él habrá acostumbrado – he will have accustomed
  • ella habrá acostumbrado – she will have accustomed
  • usted habrá acostumbrado – (formal) you will have accustomed
The first person plural has the form habremos acostumbrado. It’s created by following the same logic as in the other persons. We first take the form of the first person plural from haber conjugation in the Futuro Imperfecto de Indicativo tense: habremos. Second, to this word we again add the Participio of acostumbrar: acostumbrado to get habremos acostumbrado:
  • nosotros habremos acostumbrado – we will have accustomed
  • nosotras habremos acostumbrado – (feminine) we will have accustomed
Again, let’s do the same for the second person plural. We need to get the inflected form of the verb haber in the Futuro Imperfecto de Indicativo tense, second person plural, and it’s habréis. Next, we take the unchanged Participio, we join them, and we get habréis acostumbrado:
  • vosotros habréis acostumbrado – (plural) you will have accustomed
  • vosotras habréis acostumbrado – (feminine, plural) you will have accustomed
And finally, the last grammatical person on the list, the third person plural, has the form habrán acostumbrado. We create it in the exact same manner as in all the other grammatical persons. We need the third person plural of haber first, from its Futuro conjugation. It is habrán. We add the Participio of acostumbrar again (acostumbrado) to get habrán acostumbrado:
  • ellos habrán acostumbrado – they will have accustomed
  • ellas habrán acostumbrado – (feminine) they will have accustomed
  • ustedes habrán acostumbrado – (formal, plural) you will have accustomed

This is it! The conjugation is now finished. The final result looks as follows:

yohabré acostumbradoI will have accustomed
habrás acostumbradoyou will have accustomed
él/ella/ustedhabrá acostumbradohe/she/it will have accustomed
nosotros/nosotrashabremos acostumbradowe will have accustomed
vosotros/vosotrashabréis acostumbradoyou will have accustomed
ellos/ellas/ustedeshabrán acostumbradothey will have accustomed
