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 conjugated 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 Subjuntivo tense, we use the Presente de Subjuntivo (Present Subjunctive) conjugation of haber
  • Past Participle, which is always the same in every compound tense for a given verb
See the conjugation charts 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 cometer only here.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 have to begin by splitting the infinitive into a stem and an ending. It’s very 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 in case of the verb cometer it’s easy to see that:
  • the stem is: comet-
  • and the ending is: -er
Based on the ending of the infinitive we can recognize that cometer belongs to the -er verb group. This group, in turn, uses the -ido ending in its Participio form. Putting all that together, our Participio is: cometido.

And 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 Presente de Subjuntivo, which is haya. To that we add the Participio cometido to get haya cometido:
  • yo haya cometido – I have commited
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 Subjuntivo tense, and it is hayas. And to this auxiliary verb we add the Participio cometido (so the exact same word as previously) to get hayas cometido:
  • tú hayas cometido – you have commited
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 haya. Then we also take the same Participio as for all other persons, and putting them together we get haya cometido:
  • él haya cometido – he have commited
  • ella haya cometido – she have commited
  • usted haya cometido – (formal) you have commited
The first person plural has the form hayamos cometido. 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 Subjuntivo tense: hayamos. Second, and to this word we again add the Participio of cometer: cometido to get hayamos cometido:
  • nosotros hayamos cometido – we have commited
  • nosotras hayamos cometido – (feminine) we have commited
Again, let’s do the same for the second person plural. We have to get the conjugated form of the verb haber in the Presente de Subjuntivo tense, second person plural, and it is hayáis. Next, we take the unchanged Participio, we join them, and we get hayáis cometido:
  • vosotros hayáis cometido – (plural) you have commited
  • vosotras hayáis cometido – (feminine, plural) you have commited
And finally, the last grammatical person on the list, the third person plural, has the form hayan cometido. 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 hayan. We add the Participio of cometer again (cometido) to get hayan cometido:
  • ellos hayan cometido – they have commited
  • ellas hayan cometido – (feminine) they have commited
  • ustedes hayan cometido – (formal, plural) you have commited

That’s it! The conjugation is now finished. Put together, the conjugation chart looks like this:

yohaya cometidoI have commited
hayas cometidoyou have commited
él/ella/ustedhaya cometidohe/she/it have commited
nosotros/nosotrashayamos cometidowe have commited
vosotros/vosotrashayáis cometidoyou have commited
ellos/ellas/ustedeshayan cometidothey have commited
