Курсовая работа: The system of English verbs

Jean mangerait s'il avait faim, in French;

Juan comería si tuviera hambre, in Spanish.

In the Romance languages, the conditional form is used primarily in the apodosis (main clause) of conditional clauses, and also in a few set phrases where it expresses courtesy or doubt. The main verb in the protasis (dependent clause) is either in the subjunctive or in the indicative mood.

This is not a universal trait; in Finnish, for example, the conditional mood is used both in the apodosis and the protasis. An example is the sentence «I would buy a house if I earned a lot of money», where in Finnish both clauses have the conditional marker – isi– : Ostaisin talon, jos ansaitsisin paljon rahaa.

In English, too, the would + infinitive construct can be employed in main clauses, with a subjunctive sense: «If you would only tell me what's troubling you, I might be able to help».

Imperative

The imperative mood expresses direct commands, requests, and prohibitions. In many circumstances, using the imperative mood may sound blunt or even rude, so it is often used with care. Example: «Paul, do your homework now». An imperative is used to tell someone to do something without argument.

Many languages, including English, use the bare verb stem to form the imperative. Other languages, such as Seri, however, use special imperative forms.

In English, second-person is implied by the imperative except when first-person plural is specified, as in «Let's go» («Let us go»).

Interrogative

The interrogative mood is used for asking questions. Most languages do not have a special mood for asking questions, but Welsh and Nenets do.

Jussive

The jussive mood is similar to the cohortative mood, in that it expresses plea, insistence, imploring, self-encouragement, wish, desire, intent, command, purpose or consequence. In some languages, the two are distinguished in that cohortative occurs in the first person and the jussive in the second or third.

Sometimes this is called a «desiderative mood», since it indicates desires. Occasionally distinctions are made between different optative moods, e.g. a mood to express hopes as opposed to a mood to express desires. (Desires are what we want to be the case; hope generally implies an optimism toward the chances of a desire's fulfillment. If someone desires something but is pessimistic about its chances of occurring, then one desires it but does not hope for it.)

Subjunctive

The subjunctive mood, sometimes called conjunctive mood, has several uses in dependent clauses. Examples include discussing hypothetical or unlikely events, expressing opinions or emotions, or making polite requests (the exact scope is language-specific). A subjunctive mood exists in English, but native English speakers need not use it. Example: «I suggested that Paul read some books», Paul is not in fact reading a book. Contrast this with the sentence «Paul reads books», where the verb «to read» is in the present tense, indicative mood. Another way, especially in British English, of expressing this might be «I suggested that Paul should read some books», derived from «Paul should read some books.»

Other uses of the subjunctive in English, as in «And if he be not able to bring a lamb, then he shall bring for his trespass…» (KJV Leviticus 5:7) have definitely become archaic. Statements such as «I will ensure that he leave immediately» often sound archaic or overly formal, and have been almost completely supplanted by constructions with the indicative, like «I will ensure that he leaves immediately».

The subjunctive mood figures prominently in the grammar of Persian and the Romance languages, which require this mood for certain types of dependent clauses. This point commonly causes difficulty for English speakers learning these languages.

In certain other languages, the dubitative or the conditional moods may be employed instead of the subjunctive in referring to doubtful or unlikely events (see the main article).

2.5 The category of tense

Grammatical tense is a way languages express the time at which an event described by a sentence occurs. In English, this is a property of a verb form, and expresses only time-related information.

Tense, along with mood, voice and person, are four ways in which verb forms are frequently characterized, in languages where those categories apply. There are languages (mostly isolating languages, like Chinese) where tense is not expressed anywhere in the verb or any auxiliaries, but only as adverbs of time, when needed for comprehension; in the same condition, grammatical tense in certain languages can be expressed optionally (such as Vietnamese), for example, «sinh» meaning «birth» and «sanh» meaning «birthed»; and there are also languages (such as Russian) where verbs indicate aspect in addition to or instead of tense.

The exact number of tenses in a language is often a matter of some debate, since many languages include the state of certainty of the information, the frequency of the event, whether it is ongoing or finished, and even whether the information was directly experienced or gleaned from hearsay, as moods or tenses of a verb. Some grammarians consider these to be separate tenses, and some do not.

Tenses cannot be easily mapped from one language into another. While all languages have a «default» tense with a name usually translated as «present tense» (or «simple present»), the actual meaning of this tense may vary considerably.

English tenses

Viewed in the strictest linguistic sense, English has only two tenses: nonpast tense and past tense, which are shown with the verb endings – Ø and – ed.
