Irish conjugation

Last updated

Irish verb forms are constructed either synthetically or analytically.

Contents

Synthetic forms express the information about person and number in the ending: e.g., molaim "I praise", where the ending -aim stands for "1st person singular present". In this case, a pronoun is not allowed: * molaim mé is ungrammatical. Molann mé is allowed but using the -aim ending is more common.

Analytic forms are those whose endings contain no information about person and number, and a pronoun is necessary: e.g., molann sibh "you (pl.) praise", where the ending -ann expresses only the present tense, and the pronoun sibh "you" (pl.) must accompany it in order to express "2nd person plural".

In addition to the three persons, Irish also has an impersonal form (also called the "autonomous" form), which is used in forming the passive and can conveniently be translated with "one" or "someone" as the subject. Shown below are the distribution of synthetic and analytic forms in the standard language; in the dialects, other patterns may be found, although some of the most important distinctions made in certain dialects are pointed out in this article.

See Irish orthography for the pronunciation of verb endings.

Regular verbs

There are two conjugation classes of regular verbs, as illustrated below. Forms in italics are not part of the standard language. The suffixes shown change to agree with the word ending in a velarised ("broad") consonant or palatalised ("slender") consonant. In the examples below, verbs ending with "broad" consonants are shown above those ending with "slender" consonants.

In the imperfect, preterite, and conditional, a consonant-initial stem undergoes lenition (and dialectally is preceded by do), while a vowel-initial stem is prefixed by d’. A stem beginning with f + a vowel takes both, e.g. fan "wait", d'fhan sé "he waited". The preterite impersonal, e.g. fanadh "one waited", neither undergoes lenition nor receives d'. The -f- in future and conditional stems is pronounced /h/; except in the conditional 2nd person singular and the impersonal, where it remains /f/.

2nd conjugation

Second stem verbs take the same base suffixes as first conjugation verbs, but add the infix in -(a)í- (most forms), or -eo, ó- (in the future and conditional).

Roots ending in a slender consonant undergo syncope before the addition of -í-.

Irregular verbs

There are eleven irregular verbs in Standard Irish; individual dialects have a few more. Most of them are characterized by suppletion, that is, different roots are used to form different tenses. Analytic forms are indicated by the symbol +. The preterites of many irregular verbs take the nonpreterite forms of preverbal particles, i.e. an (interrogative particle) and (negative particle), instead of ar (pret. interrogative particle) and níor (pret. negative particle). Some verbs have different independent and dependent forms in certain tenses; the independent forms are used when no particle precedes the verb, and also after "if" (open conditional) and the direct relative particle a, while the dependent forms are used after all other particles.

Abair "to say"

The d- in this verb's independent forms is not lenited, and the dependent forms are slightly archaic.

Preverbal particles

Irish uses a number of preverbal particles to modify the meaning of a sentence. In a positive statement, no particle is used and the verb comes first (except in Munster Irish where do is placed before verbs in the past, habitual past and conditional, leniting the verb that follows). This is still seen in the Standard Language in said tenses, prefixed to verbs beginning with vowels, e.g. d'ól mé (Munster Irish: d'ólas) "I drank":

Negative particles

To negate a statement, the particle is used, which causes lenition; a d’ before a vowel or lenited f is omitted:

In the preterite, the particle níor is used . There is lenition but no d’.

(In Ulster, the negative particles cha(n), pret. char are also used)

Interrogative particles

To pose a simple yes/no question, the particle an is used, which causes eclipsis (no eclipsis of vowels, because an already ends with n). In the preterite ar (+ lenition) is used. The prefix d’ is omitted:

These particles are also used to introduce an indirect question:

Negative interrogative particles

To pose a negative yes/no question, the particle nach is used, which causes eclipsis (in preterite: nár + lenition):

(In Munster is used instead of nach.)

Wh-interrogative particles

To pose a wh-question, one of the interrogative particles , cad a/céard a, cathain a, cé a, conas a etc. is used.

Verbal nouns

Formation

Irish has no infinitive and uses instead the verbal noun. The verbal noun can be formed using different strategies (mostly suffixes). The most common of these are:

Usage

The verbal noun is used as the infinitive would be used in English.

D'iarr sé ormimeacht. "He asked me to go."
B'fhearr liomfanacht. "I would rather stay."

A progressive can be expressed with the preposition ag and is equivalent to the English present participle.

Tá Seán ag obair. "Seán is working."
Bhí Máire ag caint. "Máire was speaking."

A perfect tense can be formed with either of the compound prepositions tar éis or i ndiaidh and the verbal noun.

Tá sí tar éis baint an fhéir. "She has (just) mowed the grass." (cf. Hiberno-English "She is after cutting the grass.")
Bhí sé i ndiaidh ní na gcupán. "He had (just) washed the cups." (cf. Hiberno-English "He was after washing the cups.")

The subjunctive

The subjunctive covers the idea of wishing something and so appears in some famous Irish proverbs and blessings. It is considered an old-fashioned tense for daily speech (except in set phrases) but still appears often in print. E.g.,

It is important to note that when the subjunctive is used in English, it may not be used in Irish, and another tense might be used instead:

While the relative pronoun that can be omitted in English, the corresponding go is mandatory in Irish.

Fusional languages or inflected languages are a type of synthetic language, distinguished from agglutinative languages by their tendency to use a single inflectional morpheme to denote multiple grammatical, syntactic, or semantic features.

The subjunctive is a grammatical mood, a feature of an utterance that indicates the speaker's attitude toward it. Subjunctive forms of verbs are typically used to express various states of unreality such as wish, emotion, possibility, judgment, opinion, obligation, or action that has not yet occurred; the precise situations in which they are used vary from language to language. The subjunctive is one of the irrealis moods, which refer to what is not necessarily real. It is often contrasted with the indicative, a realis mood which principally indicates that something is a statement of fact.

<span class="mw-page-title-main">English verbs</span> Verbs in the English language

Verbs constitute one of the main parts of speech in the English language. Like other types of words in the language, English verbs are not heavily inflected. Most combinations of tense, aspect, mood and voice are expressed periphrastically, using constructions with auxiliary verbs.

The morphology of Irish is in some respects typical of an Indo-European language. Nouns are declined for number and case, and verbs for person and number. Nouns are classified by masculine or feminine gender. Other aspects of Irish morphology, while typical for an Insular Celtic language, are not typical for Indo-European, such as the presence of inflected prepositions and the initial consonant mutations. Irish syntax is also rather different from that of most Indo-European languages, due to its use of the verb–subject–object word order.

The declension of Irish nouns, the definite article, and the adjectives is discussed on this page.

The Germanic language family is one of the language groups that resulted from the breakup of Proto-Indo-European (PIE). It in turn divided into North, West and East Germanic groups, and ultimately produced a large group of mediaeval and modern languages, most importantly: Danish, Norwegian, and Swedish (North); English, Dutch and German (West); and Gothic.

Irish orthography is the set of conventions used to write Irish. A spelling reform in the mid-20th century led to An Caighdeán Oifigiúil, the modern standard written form used by the Government of Ireland, which regulates both spelling and grammar. The reform removed inter-dialectal silent letters, simplified some letter sequences, and modernised archaic spellings to reflect modern pronunciation, but it also removed letters pronounced in some dialects but not in others.

Irish syntax is rather different from that of most Indo-European languages, especially because of its VSO word order.

<span class="mw-page-title-main">Irish initial mutations</span> Word initial consonantal sound changes in Irish

Irish, like all modern Celtic languages, is characterized by its initial consonant mutations. These mutations affect the initial consonant of a word under specific morphological and syntactic conditions. The mutations are an important tool in understanding the relationship between two words and can differentiate various meanings.

Middle Welsh is the label attached to the Welsh language of the 12th to 15th centuries, of which much more remains than for any earlier period. This form of Welsh developed directly from Old Welsh.

The grammar of Classical Nahuatl is agglutinative, head-marking, and makes extensive use of compounding, noun incorporation and derivation. That is, it can add many different prefixes and suffixes to a root until very long words are formed. Very long verbal forms or nouns created by incorporation, and accumulation of prefixes are common in literary works. New words can thus be easily created.

<span class="mw-page-title-main">Ulster Irish</span> Irish language dialect

Ulster Irish is the variety of Irish spoken in the province of Ulster. It "occupies a central position in the Gaelic world made up of Ireland, Scotland and the Isle of Man". Ulster Irish thus has much in common with Scottish Gaelic and Manx. Within Ulster there have historically been two main sub-dialects: West Ulster and East Ulster. The Western dialect is spoken in County Donegal and once was in parts of neighbouring counties, hence the name Donegal Irish. The Eastern dialect was spoken in most of the rest of Ulster and northern parts of counties Louth and Meath.

In the Goidelic languages, dependent and independent verb forms are distinct verb forms; each tense of each verb exists in both forms. Verbs are often preceded by a particle which marks negation, or a question, or has some other force. The dependent verb forms are used after a particle, while independent forms are used when the verb is not subject to a particle. For example, in Irish, the past tense of the verb feic has two forms: the independent form chonaic and the dependent form faca. The independent form is used when no particle precedes the verb, as in Chonaic mé Seán. The dependent form is used when a particle such as ("not") precedes the verb, as in fhaca mé Seán.

The morphology of the Welsh language shows many characteristics perhaps unfamiliar to speakers of English or continental European languages like French or German, but has much in common with the other modern Insular Celtic languages: Irish, Scottish Gaelic, Manx, Cornish, and Breton. Welsh is a moderately inflected language. Verbs conjugate for person, tense and mood with affirmative, interrogative and negative conjugations of some verbs. A majority of prepositions inflect for person and number. There are few case inflections in Literary Welsh, being confined to certain pronouns.

This article discusses the conjugation of verbs in a number of varieties of Catalan, including Old Catalan. Each verbal form is accompanied by its phonetic transcription. Widely used dialectal forms are included, even if they are not considered standard in either of the written norms: those of the Institut d'Estudis Catalans and the Acadèmia Valenciana de la Llengua. Other dialectal forms exist, including those characteristic of minor dialects such as Ribagorçan and Algherese and transitional forms of major dialects.

The grammar of the Manx language has much in common with related Indo-European languages, such as nouns that display gender, number and case and verbs that take endings or employ auxiliaries to show tense, person or number. Other morphological features are typical of Insular Celtic languages but atypical of other Indo-European languages. These include initial consonant mutation, inflected prepositions and verb–subject–object word order.
