Die toegangsure is duidelik.

In Afrikaans, the present tense of to be is always is, no matter whether the subject is singular or plural.

So you get:

• Die deur is oop. = The door is open.
• Die deure is oop. = The doors are open.

Unlike English, Afrikaans does not change this verb to are for plurals.

Die is the definite article in Afrikaans, meaning the.

A useful thing to remember is that Afrikaans uses die for:

• singular nouns
• plural nouns
• all grammatical genders

So:

• die boek = the book
• die boeke = the books
• die huis = the house

There is no separate word like English the vs something different for plural or gender.

Toegangsure is a compound noun. Afrikaans makes compounds very freely, just like Dutch and German.

It is made from:

• toegang = access / entry
• ure = hours

So toegangsure literally means something like access hours.

This is very normal in Afrikaans: instead of using a longer phrase, the language often joins words into one noun.

The singular noun is uur = hour.

Its plural is ure = hours.

So:

• een uur = one hour
• twee ure = two hours

In compounds, that plural can stay visible:

• toegangsure = access hours

This plural form is something you simply need to learn with the noun. Not all Afrikaans plurals are formed the same way.

Here duidelik comes after is, so it is being used predicatively, not directly before the noun.

Compare:

• Die toegangsure is duidelik.
  Here duidelik means clear after the verb is. No adjective ending is added.

But before a noun, Afrikaans adjectives often do take -e:

• die duidelike reëls = the clear rules
• ’n duidelike antwoord = a clear answer

So in your sentence, duidelik stays unchanged because it comes after is.

This sentence has normal main-clause word order and is very similar to English:

• Die toegangsure = subject
• is = verb
• duidelik = complement/adjective

So the pattern is:

Subject + verb + adjective

This is one of the simpler Afrikaans sentence patterns.

A rough guide for an English speaker is:

toe-gangs-uu-re

A few pronunciation notes:

• toe sounds roughly like too.
• gangs has a hard g, but in Afrikaans the g is often a throaty sound, not an English g.
• uu in ure is like the vowel in Dutch/German u/ü and may feel unfamiliar to English speakers.
• The r is usually trilled or tapped more than in most English accents.

And duidelik is roughly: doi-duh-lik or duy-duh-lik, depending on accent.

If pronunciation is your focus, duidelik is a good word to hear from native audio, because its vowel pattern can be tricky from spelling alone.

No. In this sentence, duidelik is correct, and duidelike would be wrong.

Use:

• duidelik after is
• duidelike before a noun

So:

• Die toegangsure is duidelik. = correct
• die duidelike toegangsure = also correct, but now the adjective is directly before the noun
• Die toegangsure is duidelike. = incorrect

It is a natural kind of Afrikaans compound. Afrikaans often prefers compact compound nouns where English might use a phrase.

So toegangsure sounds normal as a practical label, especially in contexts like:

• offices
• buildings
• visitor information
• schedules
• notices

You might also see other related expressions depending on context, but toegangsure is structurally very typical Afrikaans.

Yes, depending on context.

Duidelik can mean:

• clear in the sense of easy to understand
• obvious / evident
• sometimes plainly visible or clearly stated

In Die toegangsure is duidelik, the most likely idea is that the access hours are clearly stated or easy to understand.

Normally, only the first word of the sentence is capitalized, unless a proper noun appears.

So:

• Die toegangsure is duidelik.

Unlike German, Afrikaans does not capitalize all nouns.
That means toegangsure and duidelik stay lowercase here.
