How to translate Pretérito Imperfecto to English

Notice that the phrases in English in the third column of the above conjugation table are not direct translations from Spanish to English. They are usually the closest general equivalents. The example differences are:
  • In Spanish, 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 Imperfecto belongs to the simple tenses group, which means that all of the conjugated forms are one word long. There are also compound (compuesto) tenses in Spanish language, where each inflected verb form consists of two words.

The verb estar has an almost completely regular conjugation in the Pretérito Imperfecto tense of the Indicativo mood. An exception is the first person singular, which has an irregular form. It means that the other persons simply follow the general rules for this conjugation group (-ar) without further exceptions.
Image of est arThe basis for the conjugation in this tense is the stem of the verb, so we begin by splitting the infinitive into a stem and an ending. It’s very easy to do. Just remove two letters from the end of the infinitive form to get the ending — one of -ar, -er or -ir. What’s left is the stem.

So for our verb:
  • the stem is: est-
  • and the ending is: -ar
Use the stem est- in each subject as the basis for conjugation, the common prefix that each of the forms begins with.Image of est-
endings preterito imperfecto ar how to conjugate spanish verbsNext, add to this regular stem the endings specific to each person. Check out the image showing all the endings. Note both the colors and shapes of the letters. It should help you find patterns and make it easier to remember these endings.

Each grammatical person has a specific ending in each of the three conjugation groups -ar, -er, -ir.
Add the regular ending -aba for the first person singular to create estaba:
  • yo estaba
Image of -aba
Image of -abas And again add the regular ending -abas for the second person singular to create estabas:
  • tú estabas
And similarly add the regular ending -aba for the third person singular to create estaba:
  • él estaba
  • ella estaba
  • usted estaba
Image of -aba
Image of -ábamos And add the regular ending -ábamos for the first person plural to create estábamos.
Note difference in spelling

Only the first person plural has an accent here.

This difference exists only in case of the verbs from the -ar group. Other groups always have an accented i in the ending in this tense.

So add the accent to get estábamos:
  • nosotros estábamos
  • nosotras estábamos
Image of add accent  !
Image of -abais Similarly add the regular ending -abais for the second person plural to create estabais:
  • vosotros estabais
  • vosotras estabais
And as before add the regular ending -aban for the third person plural to create estaban:
  • ellos estaban
  • ellas estaban
  • ustedes estaban
Image of -aban
