Future Tense in Basque

In Brief

Basque usually forms the future by adding -ko or -go to a verb's participle and using the appropriate present-tense auxiliary: etorri → etorriko naiz (“I will come”), egin → egingo dut (“I will do it”). The main verb marks future meaning, while the auxiliary still agrees with the people and things involved in the action.

Overview

The Basque future, geroaldia, is used for events expected after the present, as well as for plans, intentions, promises, and predictions. It is introduced around B1 because forming the future ending is easy, but choosing the right auxiliary requires knowledge of Basque verb agreement.

This structure differs sharply from English will + verb. Basque does not normally insert a separate word meaning “will.” Instead, it changes the participle (the basic completed form used to build many Basque verb expressions) and follows it with a present auxiliary such as naiz, da, dut, or dugu.

The most useful beginner pattern is therefore: future-marked main verb + present auxiliary. Once that pattern is secure, the same future form can be combined with the full NOR, NOR-NORK, and NOR-NORI-NORK agreement systems.

How It Works

1. Build the future form

Start from the participle—the dictionary form commonly taught for a Basque verb—and attach the future suffix.

Participle	Future form	Example	Meaning
etorri	etorriko	etorriko naiz	I will come
ikusi	ikusiko	ikusiko dut	I will see it
hartu	hartuko	hartuko dugu	we will take it
prestatu	prestatuko	prestatuko dute	they will prepare it
egin	egingo	egingo duzu	you will do it
joan	joango	joango gara	we will go
izan	izango	izango da	it will be
egon	egongo	egongo naiz	I will be/stay

The broad spelling rule is:

• Use -ko in most cases: etorri → etorriko, ikusi → ikusiko, hartu → hartuko.
• After a participle ending in -n, the suffix is normally voiced to -go: egin → egingo, joan → joango, izan → izango, egon → egongo.

It is safest to learn frequent verbs as pairs—egin/egingo, joan/joango—rather than trying to construct every form while speaking.

2. Keep the correct auxiliary

The future ending does not decide which auxiliary to use. The verb's argument pattern does. An argument is simply a participant required by the verb, such as the person acting or the thing affected.

• NOR verbs have one core participant and normally use forms of izan: joango naiz (“I will go”), etorriko dira (“they will come”).
• NOR-NORK verbs involve an agent and a direct object (the person or thing directly affected), and normally use forms of ukan: egingo dut (“I will do it”), ikusiko zaitugu (“we will see you”).
• Verbs involving a recipient may require NOR-NORI-NORK agreement: liburua emango dizut (“I will give you the book”).

Compare the present and future. Only the main verb's aspectual form changes here; the auxiliary remains present:

Present or habitual	Future	English
Mendira joaten naiz.	Mendira joango naiz.	I go to the mountain / I will go to the mountain.
Afaria prestatzen dugu.	Afaria prestatuko dugu.	We prepare dinner / We will prepare dinner.
Egia esaten dizut.	Egia esango dizut.	I tell you the truth / I will tell you the truth.

Do not change naiz to a past form such as nintzen, or dut to nuen. The future marker is on the main verb; the auxiliary is the ordinary present form.

3. Form negatives

In a neutral negative sentence, ez comes before the conjugated auxiliary, while the future-marked main verb normally follows it:

• Ez naiz joango. — I will not go.
• Ez dut hori egingo. — I will not do that.
• Ez dizugu ezer esango. — We will not tell you anything.

This order can feel backward to an English speaker. The affirmative has joango naiz, but negation separates and reverses that pair: ez naiz joango, not ez joango naiz in the ordinary neutral pattern.

4. Ask questions

Yes/no questions can have the same basic form as statements, with question intonation and a question mark in writing:

• Bihar etorriko zara? — Will you come tomorrow?
• Hau erosiko duzu? — Will you buy this?

With a question word, place that word immediately before the focused verb group in the neutral pattern:

• Zer egingo duzu? — What will you do?
• Noiz iritsiko dira? — When will they arrive?
• Nori emango diozu liburua? — To whom will you give the book?

5. Use time expressions when they help

The future form itself marks future meaning, so a time word is not compulsory. Still, words such as bihar (“tomorrow”), gero (“later”), datorren astean (“next week”), and hemendik gutxira (“soon”) make the intended time clearer.

Basque often puts the most relevant time or topic near the beginning: Datorren urtean euskara gehiago ikasiko dut (“Next year I will study more Basque”). Word order can vary for focus, but this is a reliable neutral model.

Examples in Context

Basque	English	Note
Bihar mendira joango naiz.	Tomorrow I will go to the mountain.	joan takes a NOR auxiliary.
Zer egingo duzu asteburuan?	What will you do at the weekend?	Question word before the verb group.
Guk dena prestatuko dugu.	We will prepare everything.	NOR-NORK: “we” act on “everything.”
Ez da erraza izango.	It will not be easy.	Negative order: ez da … izango.
Datorren astean Bilbora etorriko dira.	They will come to Bilbao next week.	A clear future time expression.
Gero deituko dizut.	I will call you later.	The auxiliary agrees with the person contacted.
Afaria zortzietan hasiko da.	Dinner will start at eight.	Intransitive NOR pattern.
Ez dugu autoa erosiko.	We will not buy the car.	The future main verb follows the negative auxiliary.
Nork ekarriko du ogia?	Who will bring the bread?	nork asks for the agent.
Lagunek lagunduko digute.	Our friends will help us.	Agreement includes the people receiving help.
Euria egiten badu, etxean geratuko gara.	If it rains, we will stay at home.	A real future condition.
Hogeita hamar urte izango ditu.	He or she will be thirty years old.	A future state; in context it may also be an estimate.

Common Mistakes

Adding an English-style equivalent of “will”

• Wrong: Will joan naiz bihar.
• Right: Bihar joango naiz.
• Why: Basque marks the main verb with -ko/-go; it does not borrow English sentence structure or need a separate future auxiliary.

Using -ko after verbs ending in -n

• Wrong: Bihar joanko gara.
• Right: Bihar joango gara.
• Why: After final -n, the future suffix is normally -go: joango, egingo, izango, egongo.

Putting the negative in affirmative word order

• Wrong: Ez joango naiz.
• Right: Ez naiz joango.
• Why: In neutral negation, ez precedes the conjugated auxiliary, and the future-marked main verb follows it.

Choosing the auxiliary from the English translation

• Wrong: Hori egingo naiz.
• Right: Hori egingo dut.
• Why: egin with an object uses NOR-NORK agreement. English “I will” gives no clue about the Basque auxiliary; learn the verb's Basque agreement pattern.

Making the auxiliary future as well

• Wrong: Joango izango naiz for the simple meaning “I will go.”
• Right: Joango naiz.
• Why: The future suffix on joan is enough. Izango belongs in sentences where “be” itself has future meaning, such as pozik izango naiz (“I will be happy”).

Forgetting agreement with the object or recipient

• Wrong: Liburua emango dut zuri when the intended structure requires agreement with “you.”
• Right: Liburua emango dizut.
• Why: Standard Basque auxiliaries can encode the agent, object, and recipient. Future marking does not remove that agreement.

Usage Notes

The Basque future covers several meanings that English commonly expresses with will, be going to, or sometimes the present progressive. Bihar lan egingo dut can mean “I will work tomorrow” or, in the right context, “I am going to work tomorrow.” Basque does not force the same grammatical distinction that English often makes between a spontaneous decision and a prior plan.

For fixed schedules and events understood from context, present forms may also occur, just as English can say “The train leaves at six.” Nevertheless, the -ko/-go form is the safest explicit choice when you want to present an event as future.

The future is common in promises and assurances: Bihar deituko dizut (“I will call you tomorrow”), Ez dut ahaztuko (“I will not forget”). With first-person subjects, context often makes an intention especially prominent. With third-person subjects, prediction is often the natural reading.

Basque is spoken in several regional varieties, but the -ko/-go future pattern is standard and widely understood. Individual auxiliary forms and preferred vocabulary can vary by dialect; learners aiming at Standard Basque (euskara batua) should first master the standard agreement forms used in writing, education, and public media.

Beyond the Basics / Advanced Use

Future forms can express probability

A future form does not always locate an event after the present. In a suitable context, particularly with izan or egon, it can express a guess about the present:

• Etxean egongo da. — He or she will be at home; probably he or she is at home.
• Hogeita hamar urte izango ditu. — He or she must be about thirty.

English also uses “will” this way in sentences such as “That will be Jon at the door,” although some varieties prefer “must” or “probably.” Context tells you whether egongo da means a future location or a present inference.

Future meaning inside conditions

In a realistic condition, the clause introduced by ba- normally states the condition, while the result can use the future:

• Denbora badut, zurekin joango naiz. — If I have time, I will go with you.
• Euria egiten badu, ez gara aterako. — If it rains, we will not go out.

Do not mechanically put a future form into both clauses because English refers to future time. Basque conditional morphology has its own rules, and more hypothetical meanings use conditional auxiliary forms rather than the ordinary future alone.

Expressing “will have done”

Basque does not simply copy the English future-perfect template. A completed state at a future reference point is often expressed with context and a result construction:

• Bostetarako lana amaituta egongo da. — By five, the work will be finished.
• Zu iristerako, afaria prestatuta izango dugu. — By the time you arrive, we will have dinner prepared.

These constructions combine a result form such as amaituta (“finished”) with future egon or izan. They are useful later refinements, not part of the core B1 formation rule.

Focus can change word order

Basque word order is sensitive to focus—the information presented as the key answer or contrast. The neutral patterns in this article are dependable, but natural discourse may move a constituent to highlight it. Learn the standard affirmative and negative orders first; then notice variations in authentic speech rather than treating every different order as a new tense.

Practice Tips

1. Make three-form sets. For ten common verbs, write the participle, future form, and a complete sentence: egin → egingo → Bihar egingo dut. Include both -ko and -go verbs.
2. Transform whole sentences, not isolated verbs. Change an affirmative into a negative and then a question: Etorriko zara → Ez zara etorriko → Noiz etorriko zara? This trains the word-order change around the auxiliary.
3. Keep the auxiliary constant while changing time. Compare egiten dut / egin nuen / egingo dut. Say who acts, what is affected, and who receives it so that future formation does not distract you from agreement.

Related Concepts

• Prerequisite: Past Tense (Simple Past) — reinforces how Basque separates the main verb from the auxiliary and how the auxiliary carries agreement.
• Next step: Conditional Mood — builds future results into real conditions and introduces hypothetical ba- and -ke forms.
