Jag försöker uttala de nya orden tydligt när vi pratar svenska.

After försöka, Swedish can use either pattern:

• försöka + infinitive
• försöka att + infinitive

So both of these are possible:

• Jag försöker uttala de nya orden tydligt.
• Jag försöker att uttala de nya orden tydligt.

The version without att is very common and sounds natural.

It can mean both, depending on context.

Swedish present tense often covers both:

• a general/habitual present: I try
• an ongoing present: I am trying

So Jag försöker can mean either I try or I am trying. The rest of the sentence and the situation tell you which one is intended.

Because de nya orden is definite: it means the new words, not just new words.

Compare:

• nya ord = new words
• de nya orden = the new words

Swedish usually marks definiteness very clearly when there is an adjective before the noun.

This is a very common Swedish pattern called double definiteness.

When a noun is definite and has an adjective before it, Swedish usually uses:

• a definite article/determiner: de
• the adjective in the right form: nya
• the noun in definite form: orden

So:

• orden = the words
• de nya orden = the new words

To an English speaker, it can feel like Swedish is marking the twice. That is normal.

Because adjectives change form in Swedish.

The adjective ny changes like this:

• en ny bok = a new book
• ett nytt ord = a new word
• nya böcker = new books
• de nya orden = the new words

So nya is the form used for:

• plural nouns
• definite nouns with an adjective

Here it is both plural and definite, so nya is exactly what you expect.

Yes — and that is the tricky part.

Ord is one of those Swedish nouns whose singular and indefinite plural look the same:

• ett ord = a word
• ord = words
• ordet = the word
• orden = the words

So in your sentence:

• ord would be words
• orden is the words

Because tydligt is being used as an adverb, meaning clearly.

The adjective is tydlig = clear.
The adverb is usually formed with the -t form:

• tydlig = clear
• tydligt = clearly

So:

• ett tydligt ord = a clear word
• uttala tydligt = pronounce clearly

Because it is modifying the action uttala and fits naturally there as an adverb of manner.

Swedish often places this kind of adverb after the object:

• uttala de nya orden tydligt

That sounds natural and neutral.

You may sometimes see different word orders for emphasis, but in this sentence the placement is very standard.

Names of languages in Swedish usually do not take an article.

So you say:

• prata svenska = speak Swedish
• lära sig svenska = learn Swedish
• förstå engelska = understand English

You would not normally say den svenska here.

Yes. Both are possible, but they are used a little differently.

• pratar svenska = speak Swedish
• pratar på svenska = speak in Swedish

The version without på is very common when you simply mean knowing or using a language.

The version with på can sound a bit more like you are emphasizing the language being used in that situation.

So in your sentence, när vi pratar svenska is very natural.

Both verbs can mean speak, but prata is usually more everyday and conversational.

• prata = talk, speak
• tala = speak, often a bit more formal or formal-sounding

So:

• vi pratar svenska sounds natural and everyday
• vi talar svenska is also correct, but slightly more formal

Here när introduces a time clause.

Depending on context, it can correspond to English when, whenever, or sometimes something close to while.

In this sentence, när vi pratar svenska means something like:

• when we speak Swedish
• or, in natural English, possibly when we’re speaking Swedish

Swedish often uses när where English might choose when or while, depending on style and context.

Because när vi pratar svenska is a subordinate clause, and subordinate clauses normally have the subject before the verb:

• när vi pratar svenska

The order när pratar vi svenska would sound like a direct question:

• När pratar vi svenska? = When do we speak Swedish?

So in your sentence, the clause is not a question. It is just giving a time condition.

In everyday spoken Swedish, de is very often pronounced dom.

So although it is written de, many speakers say something like:

• dom nya orden

This is one of the most common spelling-vs-pronunciation surprises in Swedish.

Yes — several.

A few useful ones:

• försöker: stress is on the second syllable, för-SÖ-ker
• uttala: stress is on TA, so u-TA-la
• nya and tydligt contain the Swedish y, which is not the same as English y
• försöker contains ö, which is also a vowel English speakers usually need to practice separately

So the hardest sounds for many English speakers here are:

• y in nya, tydligt
• ö in försöker
• the spoken de = dom

If you want, a good next step is to practice the sentence in chunks:

• Jag försöker
• uttala de nya orden
• tydligt
• när vi pratar svenska
