Absolutive Case in Basque

In Brief

The Basque absolutive case, traditionally called NOR, marks the subject of an intransitive verb and the direct object of a transitive verb. With definite nouns, its most visible forms are singular -a and plural -ak: mutila “the boy,” mutilak “the boys.” The same -ak also has another job—the singular ergative—so the verb and the rest of the sentence help you interpret it.

Overview

A case is a form that helps show the role of a noun phrase in a sentence. A noun phrase is a noun together with words that belong to it, as in “the red apple” or “two books.” English relies heavily on word order: in “the child sees the dog,” position tells us which participant sees and which one is seen. Basque also uses word order, but case endings and verb agreement provide important clues.

The absolutive is introduced at A1 because it occurs in the simplest statements: someone arrives, something is red, children play, or a person reads a book. Basque teaching labels it NOR, from the question word nor? “who?”; for things, the corresponding question is often zer? “what?” You will meet NOR in verb-pattern names such as NOR and NORK–NOR.

The unfamiliar point for an English speaker is that Basque does not give one case to every grammatical subject. It groups together the subject of an intransitive verb (a verb without a direct object) and the direct object of a transitive verb (a verb acting on a direct object). These both take the absolutive. The doer of a transitive verb normally takes the ergative instead.

How It Works

The beginner rule: identify the NOR participant

Ask what kind of verb you have and then identify the relevant participant:

Sentence pattern	What receives the absolutive?	Example
Intransitive: someone/something comes, goes, falls, sleeps, or exists	The subject—the participant doing or undergoing that one-participant event	Mutila etorri da. “The boy has come.”
Copular: someone/something is identified or described with izan “be”	The subject being identified or described	Sagarra gorria da. “The apple is red.”
Transitive: someone sees, reads, buys, or eats something	The direct object—the person or thing directly affected	Nik liburua irakurri dut. “I have read the book.”

Compare these two sentences:

• Mutila etorri da. — “The boy has come.” Here mutila is the absolutive subject of intransitive etorri “come.”
• Mutilak liburua irakurri du. — “The boy has read the book.” Here mutilak is the ergative doer, while liburua is the absolutive object.

English calls “the boy” the subject in both translations. Basque instead asks whether the verb has a direct object. That is why learning a Basque verb together with its usual auxiliary pattern is more reliable than transferring the English label “subject.”

Definite singular and plural

The absolutive itself has no special case consonant. On definite common nouns, what you see is chiefly the number-and-determination ending already used by the article system:

Number	Form	Basque	English
Definite singular	-a	etxea	the house
Definite plural	-ak	etxeak	the houses

The ending goes at the end of the whole noun phrase, not necessarily directly after the noun:

Noun phrase	Structure	Meaning
etxe handia	etxe + handi + -a	the big house
etxe handiak	etxe + handi + -ak	the big houses
sagar gorria	sagar + gorri + -a	the red apple
sagar gorriak	sagar + gorri + -ak	the red apples

Basque adjectives usually follow the noun. Compare English “the red apple,” where “the” comes first, with Basque sagar gorria, where the definite ending appears on the final word.

Some words have a final -a as part of their lexical form. They do not normally acquire a written double aa in the definite singular:

Basic form	Definite singular	Definite plural
neska “girl”	neska “the girl”	neskak “the girls”
gauza “thing”	gauza “the thing”	gauzak “the things”

This means that a final -a is not always a detachable article. Vocabulary resources may distinguish an organic final -a from the article because the distinction matters when other suffixes are added.

Not every absolutive phrase ends in -a or -ak

The labels “singular -a, plural -ak” describe the core definite pattern, not every possible NOR phrase. Basque also has an indefinite or non-determined form (mugagabea), commonly used after numbers and quantity words. Its absolutive has no visible ending:

• bi liburu — “two books”
• ur asko — “a lot of water”
• etxe bat — “a house / one house”

Proper names and pronouns also have their own forms: Ane etorri da “Ane has come,” ni etorri naiz “I have come,” and hau erosi dut “I bought this.” Do not add -a mechanically to every absolutive expression.

The auxiliary confirms the pattern

Basque auxiliaries agree with the sentence’s core participants. At beginner level, two broad patterns are especially useful:

Pattern	Typical use	Example	What the auxiliary reflects
NOR	Intransitive clause	Haurra etorri da.	singular NOR → da
NOR	Intransitive clause	Haurrak etorri dira.	plural NOR → dira
NORK–NOR	Transitive clause	Nik liburua irakurri dut.	first-person NORK + singular NOR → dut
NORK–NOR	Transitive clause	Nik liburuak irakurri ditut.	first-person NORK + plural NOR → ditut

You do not need to master the entire auxiliary system before using the case. Still, treating the noun endings and auxiliary as one pattern helps prevent mistakes: haurrak ... dira points to plural absolutive, while haurrak ... du can point to singular ergative.

Why -ak can be ambiguous

The written ending -ak can represent two different combinations:

Form	Possible analysis	Example
-ak	definite plural absolutive	Mutilak etorri dira. “The boys have come.”
-ak	definite singular ergative	Mutilak ogia erosi du. “The boy has bought the bread.”

This is not usually confusing in a complete sentence. The verb type, the other noun phrases, and auxiliary agreement resolve the meaning. The ergative definite plural has -ek, as in mutilek “the boys” when they are the doers of a transitive verb.

Examples in Context

Basque	English	Note
Mutila etorri da.	The boy has come.	Singular absolutive subject of an intransitive verb
Haurrak jolasean dira.	The children are playing.	Plural absolutive subject; dira agrees with the plural
Ane etxean dago.	Ane is at home.	Proper name in the absolutive, with no article ending
Trena berandu iritsi da.	The train has arrived late.	The arriving participant is NOR
Sagarra gorria da.	The apple is red.	Absolutive subject with izan “be”
Etxe handiak politak dira.	The big houses are beautiful.	Plural absolutive subject; plural description
Nik liburua irakurri dut.	I have read the book.	liburua is the singular absolutive object
Amak ogia erosi du.	Mother has bought the bread.	ogia is the absolutive object; amak is ergative
Guk atea ireki dugu.	We have opened the door.	The affected object atea is NOR
Ikasleek ariketa egin dute.	The students have done the exercise.	Singular absolutive object after plural ergative ikasleek
Nik liburuak irakurri ditut.	I have read the books.	Plural absolutive object; compare plural ditut
Bi sagar erosi ditut.	I have bought two apples.	Indefinite absolutive after a number; no -ak
Ur asko edan dut.	I have drunk a lot of water.	Quantity phrase in the indefinite absolutive
Hau nahi dut.	I want this.	Demonstrative pronoun as the absolutive object

Common Mistakes

Giving every subject the absolutive

• Wrong: Mutila liburua irakurri du.
• Right: Mutilak liburua irakurri du.
• Why: The reader is the doer of a transitive verb, so it takes the ergative. The thing read, liburua, is absolutive.

Reading every -ak as a plural

• Wrong interpretation: Amak ogia erosi du = “The mothers bought the bread.”
• Right interpretation: Amak ogia erosi du = “Mother bought the bread.”
• Why: Here amak is singular ergative. A definite plural ergative subject would be amek, and the auxiliary would also reflect the plural doer: Amek ogia erosi dute.

Adding -ak after a number

• Wrong: bi liburuak erosi ditut when you simply mean “I bought two books”
• Right: Bi liburu erosi ditut.
• Why: After a cardinal number such as bi “two,” Basque normally uses the indefinite form, so the absolutive noun phrase has no plural -ak. A marked definite reading such as “the two books” belongs to a more specific construction and context.

Putting the ending on the noun before its adjective

• Wrong: etxea handi
• Right: etxe handia
• Why: In the normal noun–adjective order, the article and case information appears at the end of the noun phrase.

Choosing the auxiliary from English word order alone

• Wrong: Haurrak etorri du.
• Right: Haurrak etorri dira.
• Why: “The children” is plural NOR with intransitive etorri “come,” so the auxiliary is plural dira. The form du belongs to a transitive pattern with singular NOR.

Usage Notes

“Absolutive” does not mean “always bare.” Linguists call the case unmarked because it lacks an additional case marker comparable to ergative -k, but definite number and article material can still be visible. For practical reading, it is better to think “NOR form” than “a noun with no ending.”

Basque word order is flexible enough that position alone is not a safe guide. Liburua Jonek irakurri du can still mean “Jon read the book”: liburua remains absolutive and Jonek remains ergative even though the object comes first. Case marking and auxiliary agreement let speakers rearrange phrases for focus and information structure.

In traditional learning materials, you may see verb frames written as NOR, NOR–NORI, NORK–NOR, and NORK–NORI–NOR. These labels identify the participants encoded by the auxiliary. They are useful shorthand, but they do not replace learning how a particular verb is conventionally used.

Beyond the Basics

You do not need to master the following points at A1, but they explain forms you will encounter later.

First, verb classification does not always match an English learner’s intuition. Some Basque experiences and states use participant patterns that differ from their most natural English translations. Learn common verbs with a short model sentence and their auxiliary rather than deciding solely from the English meaning.

Second, the absolutive contrasts with the partitive ending -rik in many negative and interrogative environments. Compare affirmative Ogia badago “There is bread” with negative Ez dago ogirik “There is no bread,” or Dirua duzu “You have the money” with Dirurik baduzu? “Do you have any money?” The partitive is not an automatic replacement in every negative sentence; definiteness and intended meaning matter.

Third, predicates with “be” deserve separate attention. Adjectival predicates often show determination and number agreement, as in Sagarra gorria da and Sagarrak gorriak dira. Noun predicates can vary according to whether you classify someone, identify them as a particular person, or use a lexicalized expression. At beginner level, learn complete natural examples rather than applying -a to every English noun after “be.”

Finally, in coordination, ellipsis, and marked information structures, the relationship between overt noun phrases and auxiliary agreement can become less transparent. The central principle remains stable: absolutive marks NOR, but advanced syntax may require more than counting visible endings.

Practice Tips

1. Sort by verb pattern. Take ten short sentences and divide them into intransitive NOR and transitive NORK–NOR groups. Underline the absolutive participant in each sentence.
2. Build singular–plural pairs. Say Haurra etorri da / Haurrak etorri dira and Liburua irakurri dut / Liburuak irakurri ditut. Change the noun ending and the auxiliary together.
3. Use a three-part vocabulary card. For each new verb, record a model sentence, its participant pattern, and its auxiliary—for example, etorri da (NOR) versus liburua irakurri du (NORK–NOR). This trains the Basque pattern instead of an English word-for-word mapping.
