Absolutive Case in Basque

Overview

The absolutive case, known as NOR in Basque grammatical tradition, is the default and most common case in the language. If you are just starting out at the A1 level, this is the first case you need to understand. The good news is that the absolutive is essentially the "unmarked" case — it is the basic form of a noun with just the article suffix attached.

The absolutive case is used for two main roles: the subject of intransitive verbs (verbs without a direct object) and the direct object of transitive verbs. For example, in "The boy came" (Mutila etorri da), "the boy" is in the absolutive because "come" is intransitive. In "I read the book" (Nik liburua irakurri dut), "the book" is in the absolutive because it is the direct object.

This system is called "ergative-absolutive alignment" and is one of the most distinctive features of Basque. Unlike English, where both "The boy came" and "The boy read the book" treat "the boy" the same way, Basque treats the agent of a transitive verb differently (ergative case) while the absolutive covers everything else.

How It Works

Number	Suffix	Example	Meaning
Singular	-a	mutila	the boy
Plural	-ak	mutilak	the boys
Indefinite	(bare)	mutil bat	a boy

When to use the absolutive:

Role	Example	Translation
Subject of intransitive verb	Mutila etorri da.	The boy has come.
Direct object of transitive verb	Nik liburua irakurri dut.	I have read the book.
Predicate noun	Hura irakaslea da.	He/She is a teacher.
Subject of description	Sagarra gorria da.	The apple is red.

Key points:

• The absolutive is the citation form — the form you find in dictionaries
• It looks identical to the definite article form (-a singular, -ak plural)
• The auxiliary verb agrees with the absolutive argument in all verb paradigms

Common Mistakes

Confusing absolutive plural -ak with ergative singular -ak

• Wrong: Thinking mutilak always means "the boys"
• Right: Mutilak can mean "the boys" (absolutive plural) OR "the boy" (ergative singular)
• Why: The ergative singular and absolutive plural share the suffix -ak. Context and verb agreement clarify the meaning.

Using ergative where absolutive is needed

• Wrong: Nik etorri naiz. (with ergative "nik" for intransitive verb)
• Right: Ni etorri naiz.
• Why: The subject of an intransitive verb must be in the absolutive case. Only transitive verb subjects take the ergative.

Forgetting that objects are absolutive, not ergative

• Wrong: Marking the direct object with an ergative suffix
• Right: Direct objects always appear in the absolutive case
• Why: In Basque, the absolutive marks the "patient" — whether it is the subject of an intransitive verb or the object of a transitive one.

Practice Tips

1. When you encounter any Basque sentence, identify the verb first. Is it intransitive (uses izan/egon auxiliary) or transitive (uses ukan auxiliary)? Then determine which noun is absolutive.
2. Practice forming absolutive nouns by adding -a (singular) and -ak (plural) to bare nouns. Then build sentences around them with both intransitive and transitive verbs.
