How to translate Pretérito Perfecto Compuesto to English

Notice that the English phrases 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

Pretérito Perfecto Compuesto 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 inflected verb form is one word long.

A compound tense is indicated by the ending of the auxiliary verb, not by the ending of the main verb, which is the case in Spanish simple tenses.In the compound tenses, every person’s form consist of two parts:
  • An inflected form of the auxiliary verb haber. In case of the Pretérito Perfecto Compuesto de Indicativo tense, we use the Presente de Indicativo (Present) conjugation of haber
  • Past Participle, which is always the same in every compound tense for a given verb
See 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’re focusing 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 form and you have the ending – one of -ar, -er, -ir. What’s left is the stem.So for acostumbrar:
  • 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.

And now, as we understand how both parts used by this tense are created separately, let’s 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 Presente de Indicativo, which is he. To that we add the Participio acostumbrado to get he acostumbrado:
  • yo he acostumbrado – I have accustomed
Next, to create the form for the second person singular, we again simply take the second person singular form of haber from the Presente de Indicativo tense, and it is has. And to this auxiliary verb we add the Participio acostumbrado (so the exact same word as previously) to get has acostumbrado:
  • tú has acostumbrado – you have accustomed
Similarly, if we want to create the form for the third person singular, we conjugate haber in the Presente tense and we use the corresponding person’s form (third person singular), namely ha. Then we also take the same Participio as for all other persons, and putting them together we get ha acostumbrado:
  • él ha acostumbrado – he has accustomed
  • ella ha acostumbrado – she has accustomed
  • usted ha acostumbrado – (formal) you have accustomed
The first person plural has the form hemos 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 Presente de Indicativo tense: hemos. Second, to this word we again add the Participio of acostumbrar: acostumbrado to get hemos acostumbrado:
  • nosotros hemos acostumbrado – we have accustomed
  • nosotras hemos acostumbrado – (feminine) we have accustomed
Again, let’s do the same for the second person plural. We have to get the inflected form of the verb haber in the Presente de Indicativo tense, second person plural, and it is habéis. Next, we take the unchanged Participio, we join them, and we get habéis acostumbrado:
  • vosotros habéis acostumbrado – (plural) you have accustomed
  • vosotras habéis acostumbrado – (feminine, plural) you have accustomed
And finally, the last grammatical person on the list, the third person plural, has the form han 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 Presente conjugation. It is han. We add the Participio of acostumbrar again (acostumbrado) to get han acostumbrado:
  • ellos han acostumbrado – they have accustomed
  • ellas han acostumbrado – (feminine) they have accustomed
  • ustedes han acostumbrado – (formal, plural) you have accustomed

¡Ya está! The conjugation is now complete. That’s the final result:

yohe acostumbradoI have accustomed
has acostumbradoyou have accustomed
él/ella/ustedha acostumbradohe/she/it has accustomed
nosotros/nosotrashemos acostumbradowe have accustomed
vosotros/vosotrashabéis acostumbradoyou have accustomed
ellos/ellas/ustedeshan acostumbradothey have accustomed
