Basque Grammar

Personal pronouns in Basque (ni, hi, zu, hura, gu, zuek, haiek). Basque distinguishes familiar 'hi' from formal 'zu' in the second person singular.

Present tense of izan (to be), the most essential intransitive auxiliary. Forms: naiz (I am), zara (you are), da (he/she/it is), gara (we are), zarete (you pl. are), dira (they are).

Present tense of ukan/edun (to have), the transitive auxiliary. Agrees with both subject (ergative) and object (absolutive): dut (I have it), duzu (you have it), du (he/she has it), etc.

Basque has no indefinite article but uses the suffix -a/-ak for definite (etxea 'the house', etxeak 'the houses'). 'Bat' (one) functions as an indefinite article.

The absolutive case (NOR) is the default/unmarked case for subjects of intransitive verbs and objects of transitive verbs. Singular: -a, Plural: -ak. It is the citation form of nouns.

The ergative case (NORK) marks the subject/agent of transitive verbs. Singular: -ak, Plural: -ek. This is the key feature of Basque's ergative-absolutive alignment.

Basque follows Subject-Object-Verb word order. The verb comes at the end of the sentence, and the auxiliary follows the main verb. The element before the verb receives focus.

Basque numbers use a vigesimal (base-20) system. Basic numbers: bat (1), bi (2), hiru (3)... hogei (20), hogeita bat (21). Numbers precede the noun.

Question words in Basque: zer (what), nor (who), non (where), noiz (when), nola (how), zergatik (why), zenbat (how many). Question word comes before the verb.

Adjectives in Basque follow the noun and take the article suffix. No grammatical gender agreement. 'Etxe handia' (the big house), 'etxe handiak' (the big houses).

Basque uses postpositions (after the noun) instead of prepositions. Many are expressed through case suffixes: -n (in/at), -ra (to), -tik (from), -rekin (with), -rako (for).

Negation in Basque is formed with 'ez' placed before the auxiliary verb. In negative sentences the auxiliary moves before the main verb: 'Ez dut nahi' (I don't want).

Telling time and expressing dates. Uses 'orduak' (hours), days of the week (astelehena, asteartea...), months (urtarrila, otsaila...). Calendar uses 1eko, 2ko format.

Egon means 'to be' in the sense of location or temporary state. Uses the auxiliary 'nago, zaude, dago, gaude, zaudete, daude'. Distinguished from izan (permanent quality).

Transitive verbs require the auxiliary to agree with both subject (NORK/ergative) and object (NOR/absolutive). The auxiliary encodes who does what to whom.

Essential verbs in their basic forms: jan (eat), edan (drink), egin (do/make), joan (go), etorri (come), ikusi (see), jakin (know), nahi (want). Most use periphrastic conjugation.

Basic colours: gorria (red), urdina (blue), berdea (green), horia (yellow), zuria (white), beltza (black), arrosa (pink), laranja (orange), marroia (brown). Colours follow the noun as adjectives.

Essential food and drink vocabulary: ogia (bread), arraina (fish), haragia (meat), fruta (fruit), ura (water), ardoa (wine), esnea (milk). Ordering and expressing preferences at meals.

The indefinite (non-determined) form of nouns, used without the article suffix. Appears after numbers, quantifiers, and in certain expressions: bi etxe (two houses), etxe asko (many houses). Contrasts with the definite: etxea (the house).

Most Basque verbs use periphrastic (compound) conjugation: main verb + auxiliary. The main verb takes aspect suffixes (-ten, -tu/-du, -ko/-go) and the auxiliary carries person/number/tense agreement.

The dative case (NORI) marks the indirect object (to/for whom). Suffix: -ri (singular), -ei (plural). Triggers trivalent agreement in the auxiliary (NOR-NORI-NORK).

Past tense formed with the past forms of auxiliaries: nintzen (I was), nuen (I had it). Main verb stays in base form; the auxiliary carries the tense.

The genitive case (-ren) expresses possession. It precedes the possessed noun: 'Joneren etxea' (Jon's house). Pronouns: nire (my), zure (your), haren (his/her).

Location cases: inessiboa -n (in/at), adlatiboa -ra (to), ablatiboa -tik (from). Also: -rantz (toward), -raino (up to). Applied to nouns and pronouns for spatial relations.

The partitive suffix -rik used in negative and interrogative contexts: 'Ez dut denborarik' (I don't have time), 'Ogirik nahi duzu?' (Do you want any bread?). Contrasts with absolutive in affirmative.

Intransitive verbs with dative arguments use the NOR-NORI auxiliary paradigm: zait (to me it is), zaizu (to you it is). Used with gustatu, iruditu, mindu, and other experiencer verbs.

Future tense formed with -ko/-go suffix on the participle plus present auxiliary: 'joango naiz' (I will go), 'egingo dut' (I will do it). Also used for intentions.

Conditional sentences using 'ba-' prefix (if) on the verb and conditional auxiliary forms (-ke). 'Dirua izango banu, bidaiatu egingo nuke' (If I had money, I would travel).

Commands and requests. Basque imperative uses synthetic forms for some verbs: zatoz (come!), zoaz (go!), and periphrastic with 'ezazu' (do it). Prohibitions: 'ez + subjunctive'.

Comparisons use '-ago' suffix (handiagoa = bigger) and 'baino' (than). Superlative: '-en' suffix (handiena = the biggest). Equality: 'bezain' (as...as).

Relative clauses in Basque precede the noun and use the suffix '-n' on the verb: 'ikusi dudan gizona' (the man that I saw). No relative pronoun needed.

Additional grammatical cases: instrumentala -z (with/by means of), destinatiboa -entzat (for someone), motiboa -gatik (because of), prolatiboa -tzat (as/for the purpose of).

A few common verbs have synthetic (non-periphrastic) conjugation: joan (go) → noa/doa, etorri (come) → nator/dator, jakin (know) → dakit/daki, ekarri (bring) → dakar.

Subordinate clauses using suffixes on verbs: -la (that), -lako (because), -nez (since), -arren (although), -(e)nean (when). The subordinate clause typically precedes the main clause.

Purpose clauses with -t(z)eko (in order to): 'ikasteko' (in order to learn). Result clauses with 'hain...non' (so...that). Also '-t(z)earren' (for the sake of) and 'nahiz eta' (even though).

The progressive 'ari' construction emphasizes an action in progress: 'irakurtzen ari naiz' (I am reading right now). Also: '-tzen/-ten ari' vs. simple '-tzen/-ten' for habitual. Ari + location for 'being busy with'.

The potential mood expresses ability or possibility using '-ke-' infix in the auxiliary: daiteke (it can be), dezaket (I can do it), liteke (it could be). Different from ahal izan.

Basque does not have a true passive voice but uses impersonal constructions and nor-nork restructuring. Common patterns: indefinite subject, reflexive constructions with 'bere burua'.

Basque subjunctive uses special auxiliary forms for wishes, doubts, and hypotheticals. '-n' suffix on auxiliaries marks subjunctive: dadin (that he/she be), dezan (that he/she do it).

Indirect speech uses the suffix '-la' on the verb and may require tense shifts. 'Esan du etorriko dela' (He/She said that he/she will come). Omen/ei (reportedly) for hearsay.

Unique to Basque: verb forms that mark the gender of the addressee even when not an argument. Male addressee: '-k' forms (duk, nauk), female: '-n' forms (dun, naun). Informal register.

Verbal nouns formed with -tze/-pen suffixes turn verbs into nouns: ikastea (learning), jakitea (knowing). Used as subjects/objects and in complex constructions.

Advanced clause types: -lako/-delako (because), -nez gero (given that), -n arren (although), nahiz eta (even though), horregatik (therefore), beraz (so/therefore).

Complex relative clauses: free relatives with -n (whoever, whatever), relative clauses with postpositions ('-n etxean' = in which house), and stacked relatives for detailed description.

The most complex auxiliary paradigm: verbs agreeing with subject, direct object, and indirect object simultaneously. The auxiliary 'diot/dizut/diegu' encodes three arguments at once.

Past counterfactual conditions using past conditional auxiliaries. Complex forms: 'izan banu... egingo nukeen' (if I had been... I would have done). Requires past tense in both clauses.

Formal Basque (euskara batua literary style): complex sentence structures, formal vocabulary, nominalized constructions, and administrative language distinct from colloquial speech.

Causative forms using -arazi suffix: ikusi → ikusarazi (make see/show), jan → janarazi (make eat/feed). These add an extra argument to the verb's agreement pattern.

Advanced connectors for sophisticated discourse: hala ere (nevertheless), izan ere (indeed), alegia (that is to say), aitzitik (on the contrary), dena den (in any case).

Multiple embedded clauses, participial constructions, and complex nominalized sentences. Using -ta/-rik (having done), -tzeko moduan (in such a way that), and nested relative clauses.

Basque uses word order for focus: the focused element goes immediately before the verb. Contrastive focus, topic marking with -a/-ak da... (as for...), and the emphatic ba- prefix.

Tense agreement in complex sentences: how main clause tense governs subordinate clause tense. Present->present, past->past. Also: hypothetical sequences and mixed time references.

Major Basque dialect differences: bizkaiera, gipuzkera, lapurtera, zuberera, nafarrera. Differences in vocabulary, verb forms, and pronunciation vs. euskara batua (unified Basque).

Historical verb forms found in literature and older texts: archaic synthetic forms, the old past tense ('edin'/'ezan' auxiliaries), and classical Basque literary constructions.

Traditional Basque idioms and proverbs reflecting cultural wisdom: 'Harri baten gainean eseri' (to sit on a stone = to be firm), 'Hitzak hitz, egintzak egintza' (words are words, deeds are deeds).

Specialized administrative and legal Basque used in government, courts, and official documents of the Basque Autonomous Community. Highly nominal, complex syntax.

Language of Basque media (ETB, Berria, Argia): news register, headline conventions, broadcast speech patterns. Differences between spoken media Basque and written/literary forms.

Understanding Basque's sociolinguistic context: euskara batua vs. dialects, language revitalization (euskaldunberri/euskaldunzahar), diglossia with Spanish/French, language policy (HABE, euskaltegiak).

Pragmatic features: hedging (agian, beharbada), fillers (ba, bueno, ederki), politeness strategies (formal zu vs. familiar hi), turn-taking markers, and indirect speech acts in Basque conversation.
