Development[ edit ] When a language develops some type of inflectionsuch as verb conjugationit normally produces certain typical regular patterns by which words in the given class come to make their inflected forms.
The language may develop a number of different regular patterns, either as a result of conditional sound changes which cause differentiation within a single pattern, or through patterns with different derivations coming to be used for the same purpose.
An example of the latter is provided by the strong and weak verbs of the Germanic languages ; the strong verbs inherited their method of making past forms vowel ablaut from Proto-Indo-Europeanwhile for the weak verbs a different method addition of dental suffixes developed.
Irregularities in verb conjugation and other inflectional irregularities may arise in various ways. Sometimes the result of multiple conditional and selective historical sound changes is to leave certain words following a practically unpredictable pattern.
This has happened with the strong verbs and some groups of weak verbs in English; patterns such as sing—sang—sung and stand—stood—stood, although they derive from what were more or less regular patterns in older languages, are now peculiar to a single verb or small group of verbs in each case, and are viewed as irregular.
Irregularities may also arise from suppletion — forms of one verb may be taken over and used as forms of another. This has happened in the case of the English word went, which was originally the past tense of wend, but has come to be used instead as the past tense of go.
The verb be also has a number of suppletive forms be, is, was, etc. The regularity and irregularity of verbs is affected by changes taking place by way of analogy — there is often a tendency for verbs to switch to a different, usually more regular, pattern under the influence of other verbs.
This is less likely when the existing forms are very familiar through Spanish irregular verbs use — hence among the most common verbs in a language like be, have, go, etc. Analogy can occasionally work the other way, too — some irregular English verb forms such as shown, caught and spat have arisen through the influence of existing strong or irregular verbs.
This is generally considered to be the situation with regular English verbs — from the one principal part, namely the plain form of a regular verb the bare infinitivesuch as play, happen, skim, interchange, etc. These rules involve the addition of inflectional endings -s, -[e]d, -ingtogether with certain morphophonological rules about how those endings are pronounced, and certain rules of spelling such as the doubling of certain consonants.
Verbs which in any way deviate from these rules there are around such verbs in the language are classed as irregular.
A language may have more than one regular conjugation pattern. French verbsfor example, follow different patterns depending on whether their infinitive ends in -er, -ir or -re complicated slightly by certain rules of spelling.
A verb which does not follow the expected pattern based on the form of its infinitive is considered irregular. In some languages, however, verbs may be considered regular even if the specification of one of their forms is not sufficient to predict all of the rest; they have more than one principal part.
In Latinfor example, verbs are considered to have four principal parts see Latin conjugation for details. Specification of all of these four forms for a given verb is sufficient to predict all of the other forms of that verb — except in a few cases, when the verb is irregular.
To some extent it may be a matter of convention or subjective preference to state whether a verb is regular or irregular. In English, for example, if a verb is allowed to have three principal parts specified the bare infinitive, past tense and past participlethen the number of irregular verbs will be drastically reduced this is not the conventional approach, however.
The situation is similar with the strong verbs in German these may or may not be described as irregular. In French, what are traditionally called the "regular -re verbs" those that conjugate like vendre are not in fact particularly numerous, and may alternatively be considered to be just another group of similarly behaving irregular verbs.
The most unambiguously irregular verbs are often very commonly used verbs such as the copular verb be in English and its equivalents in other languages, which frequently have a variety of suppletive forms and thus follow an exceptionally unpredictable pattern of conjugation.
Irregularity in spelling only[ edit ] It is possible for a verb to be regular in pronunciation, but irregular in spelling. Examples of this are the English verbs lay and pay. However their spelling deviates from the regular pattern: This contrasts with fully regular verbs such as sway and stay, which have the regularly spelt past forms swayed and stayed.
The English present participle is never irregular in pronunciation, but singeing irregularly retains the e to distinguish it from singing.
Linguistic study[ edit ] In linguistic analysis, the concept of regular and irregular verbs and other types of regular and irregular inflection commonly arises in psycholinguisticsand in particular in work related to language acquisition.
In studies of first language acquisition where the aim is to establish how the human brain processes its native languageone debate among 20th-century linguists revolved around whether small children learn all verb forms as separate pieces of vocabulary or whether they deduce forms by the application of rules.
A common error for small children is to conjugate irregular verbs as though they were regular, which is taken as evidence that we learn and process our native language partly by the application of rules, rather than, as some earlier scholarship had postulated, solely by learning the forms.
In fact, children often use the most common irregular verbs correctly in their earliest utterances but then switch to incorrect regular forms for a time when they begin to operate systematically. That allows a fairly precise analysis of the phases of this aspect of first language acquisition.
Regular and irregular verbs are also of significance in second language acquisitionand in particular in language teaching and formal learning, where rules such as verb paradigms are defined, and exceptions such as irregular verbs need to be listed and learned explicitly.
In historical linguistics the concept of irregular verbs is not so commonly referenced.Speak7 will help you learn Spanish online for free, and let you explore more about Spanish grammar, vocabulary, and expressions in Spanish with Speak7.

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.
