verða vs vera: 'Be' and 'Become' | Icelandic Grammar

English leans on one tiny verb, "be," for an enormous range of meanings — I *am tired, it **will be sunny, he **got angry, we **have to leave. Icelandic divides this territory between two verbs. *vera is the stative copula: being in a state, here and now. verða is the verb of change, future, and necessity: becoming, going to be, getting, and having to. Because English collapses all of these into "be" (or smuggles "become / get / will / have to" in only when forced), English speakers systematically reach for vera where Icelandic wants verða. This page draws the line and gives you one organising question to keep them apart.

The core distinction in one sentence

vera = be (in a state); verða = become / will be / have to / get (a change, a future, or a necessity).

Almost every choice between them reduces to a single question: Am I describing a state, or a change/future/necessity? A state that simply is takes vera. A transition into a state, a prediction about the future, or an obligation takes verða.

💡

When you're tempted to use "be", stop and ask: is this a state (it simply is — vera) or a change / future / necessity (it becomes, it will be, you have to — verða)? That one question resolves the great majority of cases.

vera: the state verb

vera is the ordinary copula — linking a subject to a description, location, or identity that holds now. It is the "be" of I am, you are, she is. It does not, on its own, signal any change or future; it just states what is.

Hann er reiður — það sést á svipnum.

He is angry — you can see it on his face. (vera: a current state)

Veðrið er gott í dag, sól og logn.

The weather is good today, sun and no wind. (vera: how things are right now)

Ég er heima, komdu bara við.

I'm home, just drop by. (vera: present location/state)

The principal parts to recognise are vera → er (present) → var (past) → verið (supine). It is irregular and extremely frequent; you already know it from A1.

verða: change, future, necessity — three English notions in one verb

Here is the heart of the page. verða does several jobs that English spreads across different words. They feel unrelated in English, but in Icelandic they are one verb, because they share an underlying idea: moving into a state — whether that movement is a real change, a future realisation, or something that must come to pass.

Sense	English	Example
Change of state	become, get, turn	Hann varð reiður. "He got angry."
Future	will be, is going to be	Það verður gott veður á morgun. "The weather will be good tomorrow."
Necessity (verða að)	have to, must	Ég verð að fara. "I have to go."
Result / outcome	turn out, come to be	Úr þessu varð ekkert. "Nothing came of this."
Dynamic passive (auxiliary)	get done, be done	Þetta verður gert á morgun. "This will be done tomorrow."

The principal parts are verða → verð (present) → varð (past) → orðið (supine) — a strong verb (class 3), with the e → a → o vowel pattern and the supine orðið. Note that the present is verð / verður and the past is varð / urðu; the supine orðið is the form you'll meet in the perfect (hann er orðinn gamall "he has grown old").

1. 'Become / get' — change of state

This is the sense English speakers most often miss. verða + an adjective or noun means become that thing — a transition, not a steady state.

Hann varð reiður þegar hann heyrði fréttirnar.

He got angry when he heard the news. (verða: a change into anger — not 'was angry')

Barnið er orðið stórt — ég þekkti hana varla!

The child has grown big — I hardly recognised her! (perfect of verða: er orðið, a completed change)

Hún ætlar að verða læknir.

She's going to become a doctor. (verða + noun: become something)

Compare directly: Hann er reiður = "He is angry" (state); Hann varð reiður = "He got/became angry" (the moment he changed). Crucially, hann var reiður can only mean "he was angry" (past state) — it can never mean "he became angry." If you want "became," you must use varð.

2. 'Will be' — the future

Icelandic has no separate future tense; for predictions and scheduled future states, verða is the natural "will be." (The present of vera can also reach into the future for fixed arrangements, but for genuine "it'll be / there'll be" predictions, verða is idiomatic.)

Það verður rigning um helgina, því miður.

It's going to rain over the weekend, unfortunately. (verður: future prediction)

Ég verð heima á morgun, hringdu bara.

I'll be home tomorrow, just call. (verð: future state — 'I'll be', not 'I am')

Þetta verður gaman!

This is going to be fun! (verður: future, anticipating)

Using vera here — ég er heima á morgun — sounds off in the prediction sense: it states a present fact bolted onto a future adverb. For "I'll be home tomorrow," the future-leaning verð is the natural choice. See expressing the future for the fuller picture.

3. 'Have to / must' — verða að

verða að + infinitive is one of Icelandic's core ways of saying have to / must — an obligation or necessity. It's strong, often non-negotiable necessity ("there's no way around it").

Ég verð að fara, annars missi ég af strætó.

I have to go, otherwise I'll miss the bus. (verða að: necessity)

Þú verður að sjá þessa mynd — hún er frábær.

You have to see this film — it's brilliant. (verða að: strong recommendation/necessity)

Við urðum að bíða í tvo tíma.

We had to wait for two hours. (past urðum að: past necessity)

This is treated with the other necessity modals on the modal verða / eiga / þurfa page; the takeaway here is simply that verða is doing double duty as a necessity verb, which vera never does.

Side by side: the same adjective, two verbs

The clearest way to feel the split is to put one adjective with each verb:

vera (state)	verða (change)
Hann er veikur. — He is ill.	Hann varð veikur. — He got/fell ill.
Það er kalt. — It is cold.	Það er að verða kalt. — It's getting cold.
Hún er þreytt. — She is tired.	Hún verður þreytt á þessu. — She'll get tired of this.

Það er að verða kalt — ég sæki peysu.

It's getting cold — I'll fetch a sweater. (vera að verða: a change in progress)

English vs Icelandic: why this trips people up

English hides three different ideas inside "be." When you say "I'll be home," "he got angry," and "we have to go," you don't feel any kinship between them — English uses "be," "got," and "have to." Icelandic groups all three under verða because each is, at bottom, coming into a state. So the trap is not that verða is exotic; it's that English never taught you these belong together. The single most damaging error is using vera for "become": hann var reiður feels like a faithful translation of "he was angry → he became angry," but it can only mean the static "he was angry." Train yourself to hear var = was (state) and varð = became (change).

Common Mistakes

❌ Hann var reiður þegar hann heyrði fréttirnar.

Means 'he WAS angry', a state — not the intended 'he got angry' at that moment.

✅ Hann varð reiður þegar hann heyrði fréttirnar.

He got angry when he heard the news. (varð = became/got, a change)

var is the static past of vera ("was"); for the change into anger you need varð (past of verða).

❌ Ég er heima á morgun, hringdu bara.

States a present fact ('I am home') awkwardly attached to a future adverb.

✅ Ég verð heima á morgun, hringdu bara.

I'll be home tomorrow, just call. (verð = future 'will be')

For "I'll be" tomorrow, use the future-leaning verð, not the present er.

❌ Ég er að fara núna, ég er seinn.

Only means 'I'm leaving now' — fine for an action, but it does not express the necessity 'I have to go'.

✅ Ég verð að fara núna, ég er seinn.

I have to go now, I'm late. (verða að = have to / must)

To say have to / must, it's verða að + infinitive; plain vera cannot carry necessity.

❌ Barnið er stórt orðið síðan í fyrra.

Wrong auxiliary for a completed change — the perfect of 'become' uses verða: er orðið.

✅ Barnið er orðið stórt síðan í fyrra.

The child has grown big since last year. (perfect of verða: er orðið, agreeing)

A completed change uses the perfect of verða — er orðið (with orðið in its correct slot), not vera + adjective.

❌ Hún ætlar að vera læknir.

Says she intends to 'be' a doctor (already), not to become one through study.

✅ Hún ætlar að verða læknir.

She's going to become a doctor. (verða = become; a future change of status)

Entering a profession is becoming it — verða læknir, not vera læknir.

Key Takeaways

vera = be in a state (er, var, verið); verða = become / will be / have to / get (verð, varð, orðið, strong class 3).
The deciding question is almost always state (vera) vs change/future/necessity (verða).
verða covers three English notions at once: become (hann varð reiður), will be (það verður gott veður), and have to (ég verð að fara).
var can only mean "was" (state); for "became" you must use varð. This is the error to watch for above all.
The perfect of verða uses the supine orðið: barnið er orðið stórt "the child has grown big."
