Die plan is geheel verkeerd.

Die means the.

So Die plan = the plan.

A useful point for learners: Afrikaans uses die as the definite article for all genders and for both singular and plural in most ordinary cases. Unlike languages such as German or Dutch, you do not have to learn different forms for masculine, feminine, or neuter nouns here.

Yes. Plan in Afrikaans is a direct cognate of English plan, and it means the same thing in this sentence.

So:

• die plan = the plan

Because it looks so familiar, it is an easy word for English speakers to remember.

Here, geheel verkeerd describes the plan after the verb is. This is called a predicate adjective/adjective phrase structure.

The pattern is:

• subject
  • is
    • description

So:

• Die plan = subject
• is = is
• geheel verkeerd = completely wrong

If you put geheel before plan, it would no longer mean the same thing. In this sentence, geheel modifies verkeerd, not plan.

Geheel means entirely, completely, or wholly.

In this sentence, it strengthens verkeerd:

• verkeerd = wrong
• geheel verkeerd = completely wrong / entirely wrong

It is a bit more formal or literary than some other common Afrikaans intensifiers. In everyday speech, many speakers might also use heeltemal:

• Die plan is heeltemal verkeerd. = The plan is completely wrong.

Verkeerd usually means wrong, incorrect, or mistaken.

In different contexts it can also mean:

• morally wrong
• factually incorrect
• the wrong one
• in the wrong direction

In Die plan is geheel verkeerd, it means the plan is wrong/incorrect.

Because verkeerd comes after is and functions as a predicate adjective. In that position, Afrikaans adjectives normally do not take the attributive -e ending.

Compare:

• Die plan is verkeerd. = The plan is wrong.
  
  • predicate adjective, so verkeerd

but

• die verkeerde plan = the wrong plan
  
  • adjective before the noun, so verkeerde

This is a very important Afrikaans pattern.

Yes. That is perfectly correct.

• Die plan is verkeerd. = The plan is wrong.
• Die plan is geheel verkeerd. = The plan is completely wrong.

The version with geheel adds emphasis.

Yes, very much so.

Is is the present-tense form of wees (to be) used with a singular subject like die plan.

So the structure is very similar to English:

• The plan is wrong.
• Die plan is verkeerd.

That makes this sentence quite approachable for English speakers.

A rough guide is:

• geheel ≈ khuh-HAYL or guh-HAYL
• verkeerd ≈ fur-KEERT

A few notes:

• The g in Afrikaans is usually a harsh throat sound, not the English g in go.
• ee is usually a long vowel sound.
• d at the end of verkeerd is often not strongly released.

This is only an approximation, but it helps as a starting point.

Yes. Good natural English translations include:

• The plan is completely wrong.
• The plan is entirely wrong.
• The plan is totally wrong.

If the meaning has already been given to the learner, the main thing to notice is that geheel intensifies verkeerd.

It sounds fairly neutral in grammar, but the meaning is strong because it gives a full negative judgment of the plan.

Using geheel makes it stronger than just verkeerd. It suggests not just that the plan has a small problem, but that it is wrong in a thorough or fundamental way.

So the tone is something like:

• not especially emotional in structure
• but definitely emphatic in meaning

Yes. Some common alternatives are:

• Die plan is heeltemal verkeerd.
• Die plan is totaal verkeerd.
• Die plan is heel verkeerd.
  
  • less standard/formal than heeltemal, but you may hear it informally

All of these mean roughly The plan is completely wrong, with small differences in style and emphasis.
