Preterite vs. ImperfectMrs. O. PachecoWorld LanguageSpanish III

Preterite vs ImperfectSpanish has two past tenses: preterite and imperfect. Most verbs can be put into either tense, depending upon the meaning.Generally speaking, the preterite is used for actions in the past that are seen as completed. Use of the preterite tense implies that the past action had a definite beginning and definite end.Note: the nosotros form is the same both in present and preterite tenses. But we can usually tell if someone is referring to the past or present from the context.

12Irregular Preterite forms There are a fair number of verbs with irregular conjugation forms in the Preterite. These Irregular forms in the Preterite are said to have "radical" changes, that is, vowel and consonant changes in the root (or stem of the verb.) Furthermore, these changes occur in all of the conjugations (including the nosotros form.) These Irregular preterite changes are NOT for orthographic (spelling) reasons (like the verbs ending in -Car, -Gar and -Zar) nor are the changes in vowels similar to regular stem-changing verbs which affect certain -Ir conjugations in the Preterite. Verbs which have an Irregular Preterite form have their own conjugation - different from the established -Ar, -Er/-Ir Preterite conjugation pattern. Irregular changesAll Verbs with grossly irregular changes in the Preterite follow this conjugation:

-Ar, -Er, -Ir Irregular VerbsYo-eT-istel, ella, usted-oNosotros-imosEllos, ellas, ustedes-ieron** * Verbs with a "J" at the end of the stem drop the "i" and just use: -eronNotice that none of these conjugation endings have accent marks! Some Common Irregular verbs in the Preterite:Andar-Anduve anduviste anduvo anduvimos anduvieronConducir*-Conduje condujiste condujo condujimos condujeronDecir*-Dije dijiste dijo dijimos dijeronEstar-Estuve estuviste estuvo estuvimos estuvieronHacer-Hice hiciste hizo hicimos hicieronPoner-Puse pusiste puso pusimos pusieronPoder-Pude pudiste pudo pudimos pudieronQuerer-Quise quisiste quiso quisimos quisieronSaber-Supe supiste supo supimos supieronTener-Tuve tuviste tuvo tuvimos tuvieronTraer*-Traje trajiste trajo trajimos trajeronVenir-vine viniste vino vinimos vinieronOrthographic ChangesVerbs that end in -gar change g to gu Verbs that end in -car change c to qu Verbs that end in -zar change z to c Verbs that end in -aer, -eer, -or, -oer, and uir change i to y and ieron to yeronVerbs that end in -ucir are irregular and conjugated as follows:Producir, produje, produjiste, produjo, produjimos, produjisteis, produjeron

This is not as confusing as it may appear. Since Ser refers to existence and identification, it is nearly impossible to use this in the Preterite which handles only completed actions. This preterite conjugation form will nearly always be Ir (an action verb) rather than Ser (a descriptive verb) which is usually conjugated in the Imperfect Past tense.Also the context of a sentence or a conversation will let you know which is being used. For example: Fui al supermercado clearly means "I went to the supermarket," not *"I was to the supermarket."

Imperfect The imperfect is used for past actions that are not seen as completed. Use of the imperfect tense implies that the past action did not have a definite beginning or a definite end. Imperfect (-ar)To conjugate regular -ar verbs in the imperfect, simply drop the ending (-ar) and add one of the following:-aba-abas-aba-bamos-abais-aban

Imperfect (-er & -ir)To conjugate regular -er and -ir verbs in the imperfect, simply drop the ending (-er or -ir) and add one of the following:-a-as-a-amos-ais-an

Regular (examples) imperfect verb forms together:hablarcomervivirhablabacomavivahablabascomasvivashablabacomavivahablbamoscomamosvivamoshablabaiscomaisVivaisHablabanComanvivanThe imperfect is used for actions that were repeated habitually.Almorzbamos juntos todos los das.We would lunch together every day.Las seoras siempre charlaban por las maanas.The ladies would always chat in the mornings.

The imperfect is used for actions that "set the stage" for another action.Yo lea cuando entr mi pap.I was reading when my papa entered. (note that "entered" is preterite)

The imperfect is used for telling time and stating one's age.Eran las siete de la noche.It was seven o'clock at night.La nia tena cinco aos.The little girl was five years old.

ImperfectRemember, the imperfect is used for past actions that are not seen as completed. Use of the imperfect tense implies that the past action did not have a definite beginning or a definite end. The imperfect tells when -- in general, an action occurred.Good news! There are only three irregular verbs in the imperfect. You must simply memorize them.

Imperfect vs. Preterite II Most verbs can be put into either tense, depending upon the meaning. The preterite tells us specifically when an action took place. The imperfect tells us in general when an action took place.Some words and phrases indicate specific time frames, and therefore signal the use of the preterite. For example:ayer (yesterday), anteayer (the day before yesterday), anoche (last night), desde el primer momento (from the first moment), durante dos siglos (for two centuries), el otro da (the other day), en ese momento (at that moment), entonces (then), esta maana (this morning), esta tarde (this afternoon) ,la semana pasada (last week), el mes pasado (last month), el ao pasado (last year), hace dos das, aos (two days, years ago), ayer por la maana (yesterday morning), ayer por la tarde (yesterday afternoon)

Other words and phrases indicate repetitive, vague or non-specific time frames, and therefore signal the use of the imperfect:a menudo (often), a veces (sometimes), cada da (every day), cada semana (every week), cada mes (every month), cada ao (every year), con frecuencia (frequently), de vez en cuando (from time to time), en aquella poca (at that time), frecuentemente (frequently), generalmente (usually), muchas veces (many times), mucho (a lot), nunca (never), por un rato (for awhile), siempre (always), tantas veces (so many times), todas las semanas (every week), todos los das (every day), todo el tiempo (all the time), varias veces (several times)

Imperfect (clues)One way to determine if a verb is actually the imperfect is to try substituting one of the following:was/were ...ingused to ...would (meaning used to) ...The following examples show how to use this substitution test for the imperfect:worked in the agency during the day.I was working in the agency during the day.I visited my grandmother every day.I used to visit my grandmother every day.Every afternoon I took a nap.Every afternoon I would take a nap.One does not normally think of a general mental state or physical sensations as having a definite beginning or end, and so they are usually expressed in the imperfect.Ramn tena miedo de hablar en pblico.Ramn was afraid to speak in public.Yo crea que Juan poda hacerlo.I thought that Juan could do it.Me gustaba el coche.I liked the car. (The car was pleasing to me.)The imperfect is used to describe how things were or what things were like. Use the imperfect when describing the characteristics of people, things or conditions.Era un muchacho muy inteligente.He was a very intelligent boy.Era una seorita muy guapa.She was a beautiful young lady.Las ventanas estaban abiertas.The windows were open.La casa era blanca.The house was white.

Preterite vs Imperfect IIIThe preterite is used for actions that are viewed as completed, while the imperfect is used for actions that did not have a definite beginning or a definite end.Estudi dos horas.I studied two hours.(completed action)Yo estudiaba antes de los exmenes.I used to study before the tests.(no definite beginning or end)Some verbs actually change meaning, depending upon whether they are used in the preterite or the imperfect. This is not surprising, since the difference in meaning can be traced back to the different way in which these two past tenses are used.conocerQuererno querersaberPodertener

Examples ConocerQuerer Conoc a Juan hace cinco aos.I met Juan five years ago.(completed action)En aquella poca conocamos muy bien la ciudad.At that time we knew the city very well.(no definite beginning or end)

Mara quiso comprar la casa.Maria tried to buy the house.(completed action)Juan quera comprar la casa.Juan wanted to buy the house.(no definite beginning or end)

Examples No querer Saber Mara no quiso comprar la casa.Maria refused to buy the house.(completed action)Juan no quera comprar la casa.Juan did not want to buy the house.(no definite beginning or end)

Mara tuvo una carta de su mam.Maria received a letter from her mom.(completed action)Juan tena un coche nuevo.Juan used to have a new car.(no definite beginning or end)

Lets review!The preterite is used in the following situations:The imperfect is used in the following situations:For actions that can be viewed as single events For actions that were repeated a specific number of times For actions that occurred during a specific period of time For actions that were part of a chain of events To state the beginning or the end of an action

For actions that were repeated habitually For actions that "set the stage" for another past action For telling time For stating one's age For mental states (usually) For physical sensations (usually) To describe the characteristics of people, things or conditions
