Die opleidingslokaal is naby.

Here die means the.

A few useful points:

• Afrikaans uses die for the with both singular and plural nouns.
• It does not change for gender. Afrikaans does not have separate masculine/feminine/neuter forms of the.
• It is usually pronounced roughly like dee, not like the English word die.

So die opleidingslokaal means the training room.

Because Afrikaans, like Dutch and German, very often forms compound nouns by writing them as a single word.

opleidingslokaal is made up of:

• opleiding = training
• lokaal = room, classroom, hall, or venue depending on context

Together they form opleidingslokaal, literally something like training-room.

This is very normal in Afrikaans. English often uses two words where Afrikaans prefers one compound word.

Not always. lokaal can refer to a room, hall, classroom, or venue depending on context.

So opleidingslokaal usually means:

• training room
• sometimes training classroom
• sometimes training venue if the context is broader

The exact English translation depends on the situation, but the Afrikaans word itself is perfectly natural.

is is the present-tense form of to be in Afrikaans, and it is much simpler than in English.

In the present tense, Afrikaans uses is for all persons:

• ek is = I am
• jy is = you are
• hy is = he is
• ons is = we are
• hulle is = they are

So in Die opleidingslokaal is naby, is simply means is.

naby means near or nearby.

In this sentence, it works as the part that describes location:

• Die opleidingslokaal is naby.
• The training room is nearby.

English sometimes separates near and nearby more clearly, but Afrikaans often uses naby in a flexible way.

So you can think of it as a location word meaning close / nearby / near depending on context.

No ending is needed here.

In Die opleidingslokaal is naby, naby comes after is, so it is being used predicatively. In that position, Afrikaans words like this normally stay in their basic form.

That is why you get:

• Die opleidingslokaal is naby.

and not a changed form after is.

If you want to put the idea before a noun, Afrikaans often uses a different form, for example:

• die nabye dorp = the nearby town
• die nabygeleë opleidingslokaal = the nearby training room

So after is, naby is fine as it is.

Yes.

If you want to say what the training room is near, you can add that after naby:

• Die opleidingslokaal is naby die ingang. = The training room is near the entrance.
• Die opleidingslokaal is naby die ontvangs. = The training room is near reception.

In your original sentence, naby stands alone because the reference point is either obvious from context or simply not important.

Yes. This is the standard word order for a simple statement in Afrikaans:

• subject + verb + rest

So:

• Die opleidingslokaal = subject
• is = verb
• naby = complement/location word

This is very straightforward and is similar to basic English word order:

• The training room is nearby.

For a yes/no question, Afrikaans usually puts the verb first:

• Is die opleidingslokaal naby? = Is the training room nearby?

You can also ask a where question:

• Waar is die opleidingslokaal? = Where is the training room?

So the statement and question patterns are:

• Die opleidingslokaal is naby.
• Is die opleidingslokaal naby?

A rough English-style pronunciation would be:

dee OH-plei-dings-loh-KAHL is nah-BUY

A few notes:

• die sounds like dee
• is is short, like iss
• naby is roughly nah-BUY
• lokaal has stress near the end: loh-KAHL

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

You can change the article or the noun number:

• 'n opleidingslokaal is naby. = A training room is nearby.
• Die opleidingslokale is naby. = The training rooms are nearby.

Useful points:

• 'n is the Afrikaans indefinite article, meaning a / an
• die can mean the for both singular and plural
• the plural of opleidingslokaal is opleidingslokale

So the sentence pattern stays the same; you only change the noun phrase.
