Five modal verbs, five different jobs

Choose the meaning first, then build the sentence. These are the uses you will meet in this guide.

kan: Ability or possibility: what someone can do, or what is possible.
må: Necessity or obligation: what someone has to do. With ikke, it can express a prohibition.
vil: Desire or willingness in these examples: what someone wants to do. It can also express future time in other contexts.
skal: A plan, intention, or instruction: what someone is going to do or is supposed to do.
bør: Advice or a recommendation: what someone should do.

Three ways to build a negative modal sentence

The modal is the finite verb: it carries the tense and controls the word order. The action verb stays in the infinitive without å. Start with kan lese, not kan å lese or kan leser. These patterns use main clauses with pronoun subjects such as jeg, du, and vi.

1
Statement: subject → modal → ikke → action
Keep the modal close to the subject. Put ikke after the modal and before the action verb. You do not add a separate word for English “do” or “does.”
Jeg kan ikke lese skjermen.
I cannot read the screen.
2
Yes/no question: modal → subject → ikke → action
Move the modal to the front to ask a yes/no question. With a pronoun subject, ikke stays after the subject. A negative question often checks something you expected to be true.
Kan du ikke lese skjermen?
Can you not read the screen?
3
Time first: time phrase → modal → subject → ikke → action
A time phrase takes the first position, so the modal comes next and the subject follows it. The action verb stays after ikke. A phrase can contain several words and still take one position.
I kveld kan jeg ikke lese rapporten.
This evening I cannot read the report.

Common mistake: Do not move ikke to the end or conjugate both verbs. Build the core first: jeg + kan + ikke + lese. Change the opening when you need a question or a time phrase; keep the action verb in the infinitive.

Check the meaning, not just the position

Må ikke: a prohibition, not an optional task

In a rule or warning, må ikke means “must not.” To clearly say that something is unnecessary, use trenger ikke å + infinitive. Do not assume that adding ikke to må simply makes an obligation optional.

Du trenger ikke å bestille lunsj til meg.

You do not need to order lunch for me.

Vil ikke: unwillingness, not just future time

With a person choosing an action, vil ikke often means “does not want to” or “is unwilling to.” Use the situation to interpret it; English “will not” alone can hide that distinction.

Hun vil ikke bytte plass.

She does not want to change seats.

10 English–Norwegian examples

Read each sentence in English, then compare the Norwegian.

Example 1 · Daily lifeBasic
I cannot find the key in my bag.
Jeg kan ikke finne nøkkelen i vesken min.
Kan describes ability here. Ikke separates the modal kan from the infinitive finne.
Example 2 · Workplace ruleBasic
You must not share the password with customers.
Du må ikke dele passordet med kunder.
This is a rule against sharing the password. Må ikke means “must not” in this context, not “you do not need to.”
Example 3 · Daily lifeBasic
He does not want to sell his bicycle.
Han vil ikke selge sykkelen sin.
Vil expresses a wish here. Vil ikke tells us he does not want to sell it; it is not simply a prediction.
Example 4 · Work plansBasic
We are not going to use the small meeting room.
Vi skal ikke bruke det lille møterommet.
Skal describes the plan. Negating it changes the plan, while bruke remains in the infinitive.
Example 5 · Work adviceIntermediate
She should not send the invoice twice.
Hun bør ikke sende fakturaen to ganger.
Bør ikke gives advice against an action. It is a recommendation rather than the prohibition in example 2.
Example 6 · WorkIntermediate
Can you not open the attachment?
Kan du ikke åpne vedlegget?
The speaker expected the file to open and is checking the problem. The order is modal–subject–ikke–action.
Example 7 · Work plansIntermediate
Are we not going to discuss the budget today?
Skal vi ikke diskutere budsjettet i dag?
This checks an expected plan. Only skal moves to the front; diskutere stays after ikke.
Example 8 · Daily lifeIntermediate
Do you not want to keep the receipt?
Vil du ikke beholde kvitteringen?
The question asks about a wish, not an ability. English uses “do,” but Norwegian starts directly with vil.
Example 9 · Work scheduleAdvanced
Before lunch I cannot help you with the printer.
Før lunsj kan jeg ikke hjelpe deg med skriveren.
The whole time phrase occupies the first position. Kan comes second, then jeg, ikke, and the infinitive hjelpe.
Example 10 · Daily lifeAdvanced
This weekend we should not spend all our money.
Denne helgen bør vi ikke bruke alle pengene våre.
Fronting the time phrase changes the opening, not the advice: bør stays before vi, and bruke stays after ikke.
