Verbs in the English language are a lexically and morphologically distinct part of speech which describes an action, an event, or a state. While English has many irregular verbs (see a list), for the regular ones the conjugation rules are quite straightforward. Being partially analytic, English regular verbs are not strongly inflected; all tenses, aspects and moods except the simple present and the simple past are periphrastic, formed with auxiliary verbs and modals. [edit] Principal partsA regular English verb has only one principal part, the infinitive or dictionary form (which is identical to the simple present tense for all persons and numbers except the third person singular). All other forms of a regular verb can be derived straightforwardly from the infinitive, for a total of four forms (e.g. exist, exists, existed, existing) English irregular verbs (except to be) have at most three principal parts:
Strong verbs like write have all three distinct parts, for a total of five forms (e. g. write, writes, wrote, written, writing). The more irregular weak verbs also require up to three forms to be learned. The highly irregular copular verb to be has eight forms: be, am, is, are, being, was, were, been, of which only one is derivable from a principal part (being is derived from be). On the history of this verb, see Indo-European copula. Verbs had more forms when the pronoun thou was still in regular use and there was a number distinction in the second person. To be, for instance, had art, wast and wert. Most of the strong verbs that survive in modern English are considered irregular. Irregular verbs in English come from several historical sources; some are technically strong verbs (i. e. their forms display specific vowel changes of the type known as ablaut in linguistics); others have had various phonetic changes or contractions added to them over the history of English. See also: Wiktionary appendix: Irregular English verbs [edit] Infinitive and basic form[edit] FormationThe infinitive in English is the naked root form of the word. When it is being used as a verbal noun, the particle to is usually prefixed to it. When the infinitive stands as the predicate of an auxiliary verb, to may be omitted, depending on the requirements of the idiom. [edit] Uses
[edit] Third person singular[edit] FormationThe third person singular in regular verbs in English is distinguished by the suffix -s. In English spelling, this -s is added to the stem of the infinitive form: run → runs. If the base ends in a sibilant sound like /s/, /z/, /ʃ/, /tʃ/ (see Help:IPA for English) that is not followed by a silent E, the suffix is written -es: buzz → buzzes; catch → catches. If the base ends in a consonant plus y, the y changes to an i and -es is affixed to the end: cry → cries. Regardless of spelling, the pronunciation of the third person singular ending in most dialects follows regular rules:
Verbs ending in o typically add -es: veto → vetoes. The third person singular present indicative in English is notable cross-linguistically for being a morphologically marked form for a semantically unmarked one. That is to say, the third person singular is usually taken to be the most basic form in a given verbal category and as such, according to markedness theory, should have the simplest of forms in its paradigm. This is clearly not the case with English where the other persons exhibit the bare root and nothing more. In Early Modern English, some dialects distinguished the third person singular with the suffix -th; after consonants this was written -eth, and some consonants were doubled when this was added: run → runneth. [edit] Usage
[edit] ExceptionEnglish preserves a number of preterite-present verbs, such as can and may. These verbs lack a separate form for the third person singular: she can, she may. All surviving preterite-present verbs in modern English are auxiliary verbs. The verb will, although historically not a preterite-present verb, is inflected like one when used as an auxiliary; by a process of levelling it has become regular when it is a full verb: Whatever she wills to happen will make life annoying for everyone else. [edit] Present participle[edit] FormationThe present participle is formed by adding the suffix -ing to the base form: go → going. The ending in most dialects is pronounced /ɪŋ/, and the pronunciation of the root does not change. If the base ends in silent e, the e is dropped : believe → believing. If the e is not silent, the e is retained : agree → agreeing. If the base ends in -ie, the ie is changed to y: lie → lying. If:
then the final consonant is doubled before adding the suffix: set → setting; occur → occurring. In British English, as an exception, the final <l> is subject to doubling even when the last syllable is not stressed: yodel → yodelling, travel → travelling; in American English, these follow the rule: yodeling, traveling. Irregular forms include:
[edit] Uses[edit] Basic Use
NB: Other words also end in -ing, notably certain nouns formed from verbs (verbal nouns) and the gerund. These are usually considered to be different entities. However, since there is a lack of consensus for this view, these are considered here. [edit] GerundThe English gerund is that form of a verb that acts as a noun but still retains its identity as a verb. Since it has different properties from the Verbal noun in -ing (below) these two forms are usually, but not always, considered to be separate entities. The gerund has indeed been dubbed a Nounal verb to help distinguish these two uses of the -ing form, but this term is not normal.
[edit] Note on possessives and personal pronouns used with the -ing formNB: Contentious There are several possessive forms in English: possessive pronoun, possessive determiner, and the possessive case of nouns. The first governs or is governed by a verb not a noun: This book is mine [not Mine book]. The second governs or is governed by a noun (or a word acting as a noun) not a verb: my book [not This book is my]. The last can govern or be governed by either: This is Helen's book (noun) or This book is Helen's (verb). Furthermore, there is the personal pronoun which also governs or is governed by verbs not nouns: he saw her [not he book]. Since the gerund is technically a verb not a noun it might seem reasonable to assume that it should govern or be governed by a personal pronoun or a possessive pronoun. However, this is not usually accepted as correct because the gerund is in fact acting as a noun while retaining verbal properties. Hence we have as standard English:
In the first construction, reading is used as a true gerund. The second construction is often disallowed by grammars and the use of the word reading is given names like fused participle and geriple[1] since it is seen to confuse a participle with a gerund. The alternate view is to see it as a genuine particle governing a personal pronoun in the objective case (as well as a nouns as an indirect object), but this is not typical. It is more often argued, however, that both of the following are correct but with different meanings:
The first example seems to imply that Jim does not like my presence in a vehicle that flies whether I am in control of that vehicle or am merely a passenger. Again this is seen as a participle but this time only governing a direct object without an indirect object. The second example seems to comment on my abilities to control the vehicle rather than my presence in the plane. The second is again a true gerund. It could be rewritten:
The controversy extends to the use of the possessive case in nouns:
The use of the possessive pronoun is probably best avoided:
As is the use of any combination of each of these:
[edit] Verbal Nouns
[edit] Preterite[edit] FormationIn weak verbs, the preterite is formed with the suffix -ed: work → worked. If the base ends in e, -d is simply added to it: hone → honed; dye > dyed. Where the base ends in a consonant plus y, the y changes to i before the -ed is added; deny → denied. Where the base ends in a vowel plus y, the y is retained: alloy → alloyed. The rule for doubling the final consonant in regular weak verbs for the preterite is the same as the rule for doubling in the present participle; see above. Regardless of spelling, pronunciation of the ending follows simple rules in most dialects:
Many strong verbs and other irregular verbs form the preterite differently, for which see that article. [edit] Use
[edit] Past participle[edit] FormationIn regular weak verbs, the past participle is always the same as the preterite. Irregular verbs may have separate preterites and past participles; see Wiktionary appendix: Irregular English verbs. [edit] Uses
[edit] TensesEnglish verbs, like those in many other western European languages, have more tenses than forms; tenses beyond the ones possible with the five forms listed above are formed with auxiliary verbs, as are the passive voice forms of these verbs. Important auxiliary verbs in English include will, used to form the future tense; shall, formerly used mainly for the future tense, but now used mainly for commands and directives; be, have, and do, which are used to form the supplementary tenses of the English verb, to add aspect to the actions they describe, or for negation. English verbs display complex forms of negation. While simple negation was used well into the period of early Modern English (Touch not the royal person!) in contemporary English negation usually requires that the negative particle be attached to an auxiliary verb such as do or be. I go not is archaic; I do not go or I am not going are what the contemporary idiom requires. English exhibits similar idiomatic complexity with the interrogative mood, which in Indo-European languages is not, strictly speaking, a mood. Like many other Western European languages, English historically allowed questions to be asked by inverting the position of verb and subject: Whither goest thou? Now, in English, questions are often trickily idiomatic, and require the use of auxiliary verbs, though occasionally, the interrogative mood is still used in Modern English. [edit] Overview of tensesIn English grammar, tense refers to any conjugated form expressing time, aspect or mood. The large number of different composite verb forms means that English has the richest and subtlest system of tense and aspect of any Germanic language. This can be confusing for foreign learners; however, English tenses can be considered clear and systematic once one understands that, in each of the three time spheres (present, past and future), there exists a basic or simple form which can then be made either progressive (continuous), perfect, or both.
Because of the neatness of this system, modern textbooks on English generally use the terminology in this table. What was traditionally called the "perfect" is here called "present perfect" and the "pluperfect" becomes "past perfect", in order to show the relationships of the perfect forms to their respective simple forms. Whereas in other Germanic languages, or in Old English, the "perfect" is just a past tense, the English "present perfect" has a present reference; it is both a past tense and a present tense, describing the connection between a past event and a present state. However, historical linguists sometimes prefer terminology which applies to all Germanic languages and is more helpful for comparative purposes; when describing wrote as a historical form, for example, we would say "preterite" rather than "past simple". This table, of course, omits a number of forms which can be regarded as additional to the basic system:
Some systems of English grammar eliminate the future tense altogether, treating will/would simply as modal verbs, in the same category as other modal verbs such as can/could and may/might. See Grammatical tense for a more technical discussion of this subject. [edit] Present simple
Note that the "simple present" in idiomatic English often identifies habitual or customary action:
It is used with stative verbs:
It can also have a future meaning (though much less commonly than in many other languages):
The present simple has an intensive or emphatic form with "do": He does write. In the negative and interrogative forms, of course, this is identical to the non-emphatic forms. It is typically used as a response to the question Does he write, whether that question is expressed or implied, and says that indeed, he does write. The different syntactic behavior of the negative particle not and the negative inflectional suffix -n't in the interrogative form is also worth noting. In formal literary English of the sort in which contractions are avoided, not attaches itself to the main verb: Does he not write? When the colloquial contraction -n't is used, this attaches itself to the auxiliary do: Doesn't he write? This in fact is a contraction of a more archaic word order, still occasionally found in poetry: *Does not he write? [edit] Present progressiveOr present continuous.
This form describes the simple engagement in a present activity, with the focus on action in progress "at this very moment". It too can indicate a future, particularly when discussing plans already in place: I am flying to Paris tomorrow. Used with "always" it suggests irritation; compare He always does that (neutral) with He is always doing that (and it annoys me). Word order differs here in the negative interrogative between the more formal is he not writing and the colloquial contraction isn't he writing? [edit] Present perfectTraditionally just called the perfect.
This indicates that a past event has one of a range of possible relationships to the present. This may be a focus on present result: He has written a very fine book (and look, here it is, we have it now). Alternatively, it may indicate a period which includes the present. I have lived here since my youth (and I still do). Compare: Have you written a letter this morning? (it is still morning) with Did you write a letter this morning? (it is now afternoon). The perfect tenses are frequently used with the adverbs already or recently or with since clauses. Although the label “perfect tense” implies a completed action, the present perfect can identify habitual (I have written letters since I was ten years old.) or continuous (I have lived here for fifteen years.) action. In addition to these normal uses where the time frame either is the present or includes the present, the “have done” construct is used in temporal clauses to define a future time: When you have written it, show it to me. It also forms a perfect infinitive, used when infinitive constructions require a past perspective: Mozart is said to have written his first symphony at the age of eight. (Notice that if not for the need of an infinitive, the simple past would have been used here: He wrote it at age eight.) The past infinitive is also used in the conditional perfect. [edit] Present perfect progressiveOr continuous.
Used for unbroken action in the past which continues right up to the present. I have been writing this paper all morning (and still am). Present Perfect Continuous is used for denoting the action which was in progress and has just finished (a) or is still going on (b). For example,
If we have to ask a question with “How long…?” we should use the present perfect continuous. For example,
However, with stative words (such as see, want, like, etc), or if the situation is considered permanent, we should use the present perfect simple. For example,
If we talk about the whole period, we use “for” and when we talk about the starting point of the action, we use “since”. We should not use the present simple tense for denoting actions that began in the past and are still going on. For example,
[edit] Past simpleOr preterite. In older textbooks often called the imperfect.
The same This tense is used for a single event in the past, sometimes for past habitual action, and in chronological narration. Like the present simple, it has emphatic forms with "do": he did write. Although it is sometimes taught that the difference between the present perfect and the past simple is negligable, the two are quite distinct:
The "used to" past tense for habitual actions is probably best included under the bracket of the past simple. Compare:
[edit] Past continuousOr imperfect or past progressive.
This is typically used for two events in parallel:
Or for an interrupted action (the past simple being used for the interruption):
Or when we are focusing on a point in the middle of a longer action:
[edit] Past perfectOr "pluperfect"
This is used to indicate that the verb refers back to a time in the past prior to another time also in the past. This latter could be stated explicitly:
Or understood from previous information:
Or simply implied from the usage itself:
It is sometimes possible to use the Simple Past instead of the Past Perfect, but only where there is no ambiguity in the meaning: The second example could be written:
Within the rest of the context, this still means that I first invited Jim then later ate the meal (without him). Consider the following, however:
This means that he left and, at the same time, we arrived. Care is required in choosing the correct wording! The following do mean the same:
The former still seems to imply a causal connection between the the two verbs, however, eg he left because he knew we were coming. The latter sentence does not have the same implication, though it also does not rule out any causal connection. Past Perfect can also be used to express a counterfactual statement:
Here, the first clause refers to an unreal state in the past, and the entire construction is a conditional sentence. [edit] Past perfect progressiveOr "pluperfect progressive" or "continuous"
Relates to the past perfect much as the present perfect progressive relates to the present perfect, but tends to be used with less precision. [edit] Future simple
See the article Shall and Will for a discussion of the two auxiliary verbs used to form the simple future in English. There is also a future with "go" which is used especially for intended actions, and for the weather, and generally is more common in colloquial speech:
The will future, however, is preferred for spontaneous decisions:
The will future is also used for statements about the present to indicate that they are speculative:
[edit] Future progressive
Used especially to indicate that an event will be in progress at a particular point in the future: This time tomorrow I will be taking my driving test. [edit] Future perfect
Used for something which will be completed by a certain time (perfect in the literal sense) or which leads up to a point in the future which is being focused on.
[edit] Future perfect progressiveOr future perfect continuous.
Used for an event that will be in progression at a certain point in the future. "He will have been writing by 8:00 am (and will continue writing further into the future)." [edit] ConditionalOr past subjunctive.
Used principally in a main clause accompanied by an implicit or explicit doubt or "if-clause"; may refer to conditional statements in present or future time:
(A very common error by foreign learners is to put the would into the if-clause itself. A humorous formulation of the rule for the classroom runs: "If and would you never should, if and will makes teacher ill!" Nevertheless, of course, both will and would can occur in an if-clause when expressing volition. A student of English may rarely encounter the incorrect construction as it can occur as an archaic form.) [edit] Conditional progressive
Used as the continuous tense of the conditional form; describes a situation that would now be prevailing had it not been for some intervening event:
[edit] Conditional perfectOr pluperfect subjunctive/past-perfect subjunctive.
Used as the past tense of the conditional form; expresses thoughts which are or may be contrary to present fact:
[edit] Conditional perfect progressive
[edit] Present subjunctiveThe form is always identical to the infinitive. This means that, apart from the verb "to be", it is distinct only in the third person singular and the obsolete second person singular.
Used to refer to situations which are or may be contrary to fact in the present or future; the infactuality is rarely explicit:
(The present subjunctive is often interchangeable with the past subjunctive like so: I insist that he must come at once.) [edit] Imperfect subjunctiveThe use of the old term "imperfect" shows that this form is so rare that it has not been integrated into the modern system of English tense classification. The imperfect subjunctive is identical to the past simple in every verb except the verb "to be". With this verb, there is an option, but no longer a necessity, of using were throughout all forms (i.e., I wish I were an Oscar Meyer wiener, vs. I wish I was a girl).
