Imperfect tense
From Wikipedia, the free encyclopedia
The imperfect tense, in the classical grammar of several Indo-European languages, denotes a past tense with an imperfective aspect. It corresponds to the English past-continuous tense. In contrast, the imperfect tense in Hebrew grammar is called thus because it refers to "uncompleted" action and therefore denotes present or future time.

[edit] English
In English, the imperfect tense is manifested in the verb phrases:
- I was eating.
- I used to eat.
In modern linguistics, and especially in TEFL contexts, it is more usual to refer to this as the "past progressive" tense.
[edit] Romance languages
In Romance languages, the imperfect is generally a past tense. Its uses include representing:
- An action that was happening, used to happen, or happened regularly in the past and on going
- People, things, or conditions of the past
- A physical or mental state or condition in progress in the past. Often used with verbs of being, emotion, capability, or conscience. The following verbs are often used in the imperfect in several Romance languages:
-

English equivalent French Spanish Italian Portuguese to love aimer amar amare amar to desire desirer desear desiderare desejar to want vouloir querer volere querer to prefer préférer preferir preferire preferir to hope éspérer esperar sperare esperar to feel sentir sentir sentire sentir to regret/lament regretter lamentar rimpiangere lamentar to be être ser/estar essere ser/estar to be able to pouvoir poder potere poder to know (a person) connaître conocer conoscere conhecer to know (a thing) savoir saber sapere saber to believe croire creer credere crer to think penser pensar pensare pensar to imagine imaginer imaginar immaginare imaginar to stand/stay attender quedar stare ficar
-
- A time in the past
- A situation that was in progress in the past when another isolated and important event occurred
A common mistake of beginners learning a Romance language is putting too much emphasis on whether the time the action occurred is known. This generally does not affect how the imperfect tense is used. For example, the sentence "Someone ate all my cookies." (when translated) is not a good candidate for the imperfect. Fundamentally, it is no different than the sentence "We ate all the cookies." On the other hand, "I used to have fun in the 1960s." is a good candidate for the imperfect, even though the time frame is known. In short, knowing when an action occurred is not nearly as important as how long it occurred (or was and still is occurring).
[edit] French
In order to form the imperfect tense for French regular verbs, add an ending to the present tense stem (the nous form without the -ons ending) of the verb:
| je | -ais |
| tu | -ais |
| il | -ait |
| nous | -ions |
| vous | -iez |
| ils | -aient |
Examples:
| parler | choisir | vendre | être | commencer | manger | étudier | |
|---|---|---|---|---|---|---|---|
| je | parlais | choisissais | vendais | étais | commençais | mangeais | étudiais |
| tu | parlais | choisissais | vendais | étais | commençais | mangeais | étudiais |
| il | parlait | choisissait | vendait | était | commençait | mangeait | étudiait |
| nous | parlions | choisissions | vendions | étions | commencions | mangions | étudiions |
| vous | parliez | choisissiez | vendiez | étiez | commenciez | mangiez | étudiiez |
| ils | parlaient | choisissaient | vendaient | étaient | commençaient | mangeaient | étudiaient |
Notes:
- Verbs that terminate in a stem of -cer and -ger undergo minor orthographic changes to preserve the phonetic sound or allophone. Verbs, whose root terminates in the letter "i", maintain the letter despite the consecutiveness in the "nous" and "vous" forms.

Conjugation of the imperfect indicative:
| hablar | comer | insistir | ir | ser | ver | |
|---|---|---|---|---|---|---|
| yo | hablaba | comía | insistía | iba | era | veía |
| tú | hablabas | comías | insistías | ibas | eras | veías |
| él | hablaba | comía | insistía | iba | era | veía |
| nosotros | hablábamos | comíamos | insistíamos | íbamos | éramos | veíamos |
| vosotros | hablabais | comíais | insistíais | ibais | erais | veíais |
| ellos | hablaban | comían | insistían | iban | eran | veían |
Notes:
- There are only three irregular verbs in the imperfect tense: ir, ser, and ver.
- The yo and el/ella/usted forms are the same for verbs ending in ar, er, and ir; thus, in the cases of subjective ambiguity where context be insufficient, a pronoun or subjective noun is included for the sake of clarification.

Conjugation of the imperfect indicative:
| avere | essere | parlare | credere | finire | dire | opporre | |
|---|---|---|---|---|---|---|---|
| io | avevo | ero | parlavo | credevo | finivo | dicevo | opponevo |
| tu | avevi | eri | parlavi | credevi | finivi | dicevi | opponevi |
| lui | aveva | era | parlava | credeva | finiva | diceva | opponeva |
| noi | avevamo | eravamo | parlavamo | credevamo | finivamo | dicevamo | opponevamo |
| voi | avevate | eravate | parlavate | credevate | finivate | dicevate | opponevate |
| loro | avevano | erano | parlavano | credevano | finivano | dicevano | opponevano |
Notes:
- Verbs are formed by dropping the -re suffix and adding -vo, -vi, -va, -vamo, -vate, and -vano.
- There is only one irregular verb in the imperfect tense: essere.
- Although dire and opporre may seem irregular, they are a part of a verb family that has stronger roots to Latin equivalents. Other verbs include fare, bere, and ridurre.

Conjugation of the imperfect indicative:
| parāre | docēre | legere | capere | scīre | esse | |
|---|---|---|---|---|---|---|
| ego | parābam | docēbam | legēbam | capiēbam | sciēbam | eram |
| tū | parābās | docēbas | legēbās | capiēbās | sciēbās | erās |
| is | parābat | docēbat | legēbat | capiēbat | sciēbat | erat |
| nōs | parābāmus | docēbāmus | legēbāmus | capiēbāmus | sciēbāmus | erāmus |
| vōs | parābātis | docēbātis | legēbātis | capiēbātis | sciēbātis | erātis |
| eī | parābant | docēbant | legēbant | capiēbant | sciēbant | erant |
Notes:
- The imperfect tense is signified by the signs ba and bā.
- The imperfect tense forms of esse are used as auxiliary verbs in the pluperfect tense of the passive voice along with perfect passive participles.
[edit] Persian
Like all other past tenses, imperfect is conjugated regularly for all verbs. Formation: [preverb] + mi- + past stem + past ending
| raftan (to go) | kâr kardan (to work) | |
|---|---|---|
| 1st sg. | miraftam | kâr mikardam |
| 2nd sg. | mirafti | kâr mikardi |
| 3rd sg. | miraft | kâr mikard |
| 1st pl. | miraftim | kâr mikardim |
| 2nd pl. | miraftid | kâr mikardid |
| 3rd pl. | miraftand | kâr mikardand |
- Persian has separate tenses for past continuous and imperfect.
- In Persian the prefix mi gives imperfective aspect to the tense. For example, the mentioned imperfect tense has been built by prefixing mi to simple past. Therefore, it's possible to coin new imperfective tenses.

[edit] Hebrew
Biblical Hebrew had only two aspects (not tenses). The perfect aspect was used for completed actions, and generally implies past time. The imperfect aspect was used for uncompleted actions, and thus could imply present or future time. Modern Hebrew uses the participle for the present time and reserves the imperfect for future time. The Hebrew imperfect is noteworthy for having not only suffixes but also a syllable added at the beginning of the stem, and thus is often called the prefix conjugation.

[edit] Malayalam
In Malayalam (verbs are never conjugated for grammatical person, which is indicated by a pronoun), there are two indicative imperfect tenses, corresponding exactly with English:
- 1 -ഉകയായിരുന്നു (ukayāyirunnu) endings (... was...), for example:
- ഓടുകയായിരുന്നു (ōṭukayāyirunnu) ... was running
- 2 -ഉമായിരുന്നു (umāyirunnu) endings (... used to ...), for example:
- ഓടുമായിരുന്നു (ōṭumāyirunnu) ... used to run
- To form the "was doing" imperfect tense, take the infinitive ending in ആന് (ān), remove this ending and add ഉക (uka), for example ഓടുക (ōṭuka) - to run - and add the ending - യായിരുന്നു (yāyirunnu).
- To form the "used to do" imperfect tense, take off the ക (ka) from the end of the "uka" form and add മായിരുന്നു (māyirunnu) in its stead.
To make a verb in the imperfect negative, add അല്ല് (all) after the ഉകയ (ukaya) part of the ending for the "was doing" imperfect tense. For example, ഓടുകയല്ലായിരുന്നു (ōṭukayallāyirunnu) (...was not running). To do the same for the "used to do" imperfect, take off the ഉമ (uma) from the ending and add അത്തില്ല് (attill) instead. For example, ഓടത്തില്ലായിരുന്നു (ōṭattillāyirunnu) (...used not to run)en:Preterite
