Advanced Unit 02: Modality, Ability, Permission, Obligation, and Possibility

Learn to translate English modal verbs into precise Common Kai by separating wanting, needing, ability, permission, obligation, advice, and possible outcomes.

learner boundary

Common Kai first

Advanced work may compare technical, poetic, symbolic, and sacred choices. Start with exact Common Kai: the claim, condition, cause, request, or definition must be recoverable before register analysis.

• Write the literal Common Kai sentence first.
• Label technical, poetic, or sacred pressure separately.
• Do not make legal, medical, safety, or practical instructions poetic.

Objectives

• Separate English "can", "may", "must", "should", and "might" into precise Kai meanings.
• Use li, nive, kiri, vari, lano li, sai li, and an-vai with correct scope.
• Ask and answer permission questions.
• Distinguish ability, permission, and possibility in stories and practical dialogue.
• Negate modal statements without changing the intended meaning.
• Embed modal clauses after va.
• Use modality inside real and unreal conditions.
• Translate compressed English modal sentences into clear Common Kai.

Core Idea

English modal verbs are compressed.

Common Kai does not use one word for every English modal.

It asks what kind of pressure, freedom, or uncertainty is present.

The advanced skill is not memorizing the table.

The advanced skill is choosing the exact meaning before you translate.

The English Modal Problem

English "can" can mean at least three different things.

English "may" can mean permission or possibility.

English "must" can mean rule, obligation, strong inference, or emotional pressure.

Common Kai v0.4 only has a stable general obligation pattern for rule-like necessity:

Lano li mi yare.

The rule requires me to go. / I must go.

For inference, do not force lano li.

Instead, write what is known.

Mi e miri va Maria en noa.

I understand that Maria is at home.

Wanting with li

Use li for desire or intended direction of will.

Wanting is not the same as needing, being able, being allowed, or being required.

Compare:

If English says "Maria has to go", ask whether the source is a rule, a need, a plan, or pressure from another person.

Needing with nive

Use nive for need.

The common pattern is:

subject el nive thing

For "need to do", use a purpose-style complement with li.

This is not the same as lano li.

Maria el nive li yare.

Maria needs to go.

Lano li Maria yare.

Maria must go. / A rule requires Maria to go.

Ability with kiri

Use kiri when the issue is capacity, strength, skill, access to means, or practical ability.

Pattern:

subject e kiri li action

Ability answers:

Can the person do it?

Does the person have the strength, skill, time, health, or means?

It does not answer whether the person is allowed.

Permission with vari

Use vari when the issue is permission, allowance, authorization, or social acceptance.

Pattern:

subject e vari li action

Permission answers:

Is it allowed?

Does a person, rule, promise, or group permit it?

It does not answer whether the person can physically do it.

Explicit Permission Requests with ma vari

Use ma vari for explicit permission requests.

Reference pattern:

Ma vari va mi el yare ya?

May I go?

Short answer:

Sai, ti vari el yare.

Yes, you may go.

General permission statement:

Ti e vari li yare.

You are allowed to go.

The ma vari request is useful in dialogue when the speaker is asking for permission from the listener.

Obligation with lano li

Use lano li when a rule, law, agreement, duty, or strong obligation requires an action.

Pattern:

lano li subject action

lano li is stronger and more external than nive.

Mi el nive li yare.

I need to go.

Lano li mi yare.

I must go. / A rule requires me to go.

Advice with sai li

Use sai li for should, ought to, advisable, or morally/practically better action.

Pattern:

sai li subject action

Advice is not obligation.

Sai li Aleso hole en noa.

Aleso should stay home.

Lano li Aleso hole en noa.

Aleso must stay home.

Possibility with an-vai and anvai

Use an-vai before the predicate for might or possible future.

Use anvai as a sentence-level "maybe / perhaps".

an-vai belongs inside the clause.

anvai comments on the whole sentence.

Ability, Permission, and Possibility

Advanced translators must separate these three.

They can combine.

In advanced writing, do not let English "can" hide the difference.

Modal Questions

Keep the modal meaning clear in questions.

This is one of the most important advanced habits.

When English asks "Can you go?", decide whether the speaker is asking about ability, permission, or possibility.

Negated Modality

Place sha where the negative meaning belongs.

For "must not", use a prohibition or a rule requiring a negative action.

Do not use the same Kai sentence for "not allowed", "not able", and "might not".

They are different meanings.

Modal Scope

Modal scope means what part of the sentence the modal affects.

Compare:

Maria sha e vari li yare.

Maria is not allowed to go.

Sai li Maria sha yare.

Maria should not go.

The first is about permission.

The second is about advice against the action.

Compare:

Maria e kiri li sha yare.

Maria is able to not go.

Maria sha e kiri li yare.

Maria is not able to go.

The second sentence is usually what learners mean when translating "Maria cannot go."

If the scope feels delicate, split the sentence or choose a clearer expression.

Embedded Modality with va

Modal clauses can be embedded after va.

The embedded clause keeps its ordinary modal order.

Do not move the modal marker to the main clause unless the main clause itself has the modal meaning.

Conditions and Counterfactual Modality

Real or open condition:

An va Maria e kiri li yare, Maria an yare.

If Maria can go, Maria will go.

Permission condition:

An va Maria e vari li yare, Maria an yare.

If Maria is allowed to go, Maria will go.

Need condition:

An va Maria el nive li yare, Aleso an hile Maria.

If Maria needs to go, Aleso will call Maria.

Unreal or remembered condition:

An va Maria um e kiri, Maria an-vai yare.

If Maria had been able, Maria might have gone.

The v0.4 standard uses um in the condition and an-vai in the result for counterfactual meaning.

Dialogue: Permission, Ability, and Rule

Read the dialogue.

Notice that the dialogue does not use one Kai word for every English modal.

Each sentence names the exact relationship: permission, ability, need, obligation, or possibility.
