English

English is an example of a language with no general imperfective. The English progressive is used to describe ongoing events, but can still be used in past tense, such as "The rain was beating down". Habitual situations do not have their own verb form (in most dialects), but the construction "used to" conveys past habitual action, as in ''I used to ski''. Unlike in languages with a general imperfective, in English the simple past tense can be used for situations presented as ongoing, such as ''The rain beat down continuously through the night''. A contrast between the progressive and imperfective is seen with

Periphrastic Hindi-Urdu verb forms (participle verb forms) consist of two elements, the first of these two elements is the aspect marker and the second element (the copula) is the common tense-mood marker. There are two independent imperfective aspects in Hindi-Urdu: ''

'', and '' Progressive Aspect.'' These two aspects are formed from their participle forms being used with the copula verb of Hindi which is होना ''honā'' (to be). However, the aspectual participles can also have the verbs रहना ''rêhnā'' (to stay/remain), आना ''ānā'' (to come) & जाना ''jānā'' (to go) as their copula. The table below shows three verbs होना ''honā'' (to be), करना ''karnā'' (to do), and मरना ''marnā'' (to die) in their aspectual infintive forms using different copulas. ''Note: some translations are approximate, and the nuance cannot be expressed exactly in English. Some aspectual forms also have the same translations in English but are not interchangeable in Hindi-Urdu.'' Now, these copula verbs (besides होना ''honā'') can themselves be converted into their participle forms and put into one of the three different aspects of Hindi-Urdu, which are '' habitual'', '' progressive'', and ''

Also, these sub-aspects are even more nuanced that it is not possible to translate each of them into English in a unique way. Some translations don't even make sense in English.''

Other languages

The imperfective aspect may be fused with the past tense, for a form traditionally called the imperfect. In some cases, such as Spanish and Portuguese, this is because the imperfective aspect occurs only in the past tense; others, such as Georgian and Bulgarian, have both general imperfectives and imperfects. Other languages with distinct past imperfectives include

''), which views a situation as a simple whole, ''without'' interior composition. (This is not the same as the '' perfect''.) Unlike most other tense–aspect category oppositions, it is typical for a language not to choose either perfective or imperfective as being generally marked and the other as being generally unmarked. In narrative, one of the uses of the imperfective is to set the background scene ("It was midnight. The room was dark. The rain was beating down. Water was streaming in through a broken window. A gun lay on the table."), with the perfective describing foregrounded actions within that scene ("Suddenly, a man burst into the room, ran over to the table, and grabbed the gun."). English does not have these aspects. However, the background-action contrast provides a decent approximation in English: :"John was reading when I entered." Here 'entered' presents "the totality of the situation referred to .. the whole of the situation is presented as a single unanalysable whole, with beginning, middle, and end all rolled into one; no attempt is made to divide this situation up into the various individual phases that make up the action of entry."Bernard Comrie, 1976. ''Aspect.'' Cambridge University Press This is the essence of the perfective aspect: an event presented as an unanalyzed whole. 'Was reading', however, is different. Besides being the background to 'entered', the form 'reading' presents "an internal portion of John's reading, ithno explicit reference to the beginning or to the end of his reading." This is the essence of the imperfective aspect. Or, to continue the quotation, "the perfective looks at the situation from the outside, without necessarily distinguishing any of the internal structure of the situation, whereas the imperfective looks at the situation from inside, and as such is crucially concerned with the internal structure of the situation, since it can both look backwards towards the start of the situation, and look forwards to the end of the situation, and indeed it is equally appropriate if the situation is one that lasts through all time, without any beginning and without any end." This is why, within the past tense, perfective verbs are typically translated into English as simple past, like 'entered', whereas imperfective verbs are typically translated as 'was reading', 'used to read', and the like. (In English, it is easiest to illustrate aspect in the past tense. However, any tense is possible: Present "John is reading as I enter", future "John will be reading when I enter", etc.: In each tense, the aspectual distinction is the same.) This aspectual distinction is not inherent to the events themselves, but is decided by how the speaker views them or wishes to present them. The very same event may be described as perfective in one clause, and then imperfective in the next. For example, :"John read that book yesterday; while he was reading it, the postman came," where the two forms of 'to read' refer to the same thing. In 'John read that book yesterday', however, ''John's reading is presented as a complete event, without further subdivision into successive temporal phases;'' while in 'while he was reading it', ''this event is opened up, so that the speaker is now in the middle of the situation of John's reading,'' as it is in the middle of this reading that the postman arrives. The perfective and imperfective need not occur together in the same utterance; indeed they more often do not. However, it is difficult to describe them in English without an explicit contrast like "John was reading when I entered."

Combination

The two aspects may be combined on the same verb in a few languages, for perfective imperfectives and imperfective perfectives. Georgian and Bulgarian, for example, have parallel perfective-imperfective and

- imperfect forms, the latter restricted to the past tense. In Bulgarian, there are parallel perfective and imperfective stems; aorist and imperfect suffixes are typically added to the perfective and imperfective stems, respectively, but the opposite can occur. For example, an imperfect perfective is used in Bulgarian for a simple action that is repeated or habitual:"Bulgarian", ''Encyclopedia of Language and Linguistics'', ed. 2 Here each sitting is an unanalyzed whole, a simple event, so the perfective root of the verb 'sat' is used. However, the clause as a whole describes an ongoing event conceived of as having internal structure, so the imperfective suffix ''-eshe'' is added. Without the suffix, the clause would read simply as ''In the evening he sat on the veranda.''
