Für den Salat würfle ich die Paprika und die Avocado.

Because für always takes the accusative case.

• der Salat = nominative
• den Salat = accusative

Since the phrase means for the salad, German requires:

• für + accusative
• so: für den Salat

This is one of the most important prepositions to memorize, because für is always followed by the accusative.

Würfle comes from the verb würfeln.

In cooking, würfeln means to dice or to cut into cubes.

So:

• Ich würfle die Paprika. = I dice the bell pepper.
• Ich würfle die Avocado. = I dice the avocado.

Be careful: würfeln can also mean to roll dice in other contexts, but here the cooking meaning is intended.

German main clauses usually put the finite verb in second position.

Here, Für den Salat has been moved to the beginning of the sentence. That takes up the first position, so the verb würfle must come next:

• Für den Salat = position 1
• würfle = position 2
• ich = comes after the verb

So the structure is completely normal:

• Für den Salat würfle ich die Paprika und die Avocado.

You could also say:

• Ich würfle die Paprika und die Avocado für den Salat.

That version is also correct, but the original puts more emphasis on for the salad.

Because in German, the verb stays in second position in a main clause, even when the subject is not first.

In English, the subject usually comes first:

• I dice the pepper...

But in German, another element can come first:

• Für den Salat würfle ich ...

When that happens, the subject ich moves after the verb.

This is a very common German pattern and does not make the sentence sound unusual.

Because both nouns are feminine singular:

• die Paprika
• die Avocado

And in the accusative, feminine singular still uses die.

So:

• nominative: die Paprika

• accusative: die Paprika

• nominative: die Avocado
• accusative: die Avocado

That is why the article does not change here.

In this sentence, Paprika means the vegetable: a bell pepper or sweet pepper.

That can be confusing for English speakers, because English paprika usually means the powdered spice. In German:

• die Paprika often means bell pepper
• the spice can also be called Paprika, but the context makes the meaning clear

Since you are dicing it together with an avocado for a salad, it clearly means the vegetable here.

Most German nouns do not change their form in the accusative. Usually, the article shows the case.

Here:

• die Paprika stays die Paprika
• die Avocado stays die Avocado

The case marking is mostly visible elsewhere, such as in den Salat, where the masculine article changes from der to den.

So the noun itself often stays the same, while the article changes if needed.

In standard German, it is more natural here to repeat the article:

• die Paprika und die Avocado

German often repeats articles in coordinated noun phrases, especially when referring to two separate items.

If you say die Paprika und Avocado, it may sound less natural or incomplete to many speakers. For learners, repeating the article is the safest choice.

Here it is most naturally understood as singular: the bell pepper.

That is because it is paired with another singular noun:

• die Paprika und die Avocado

So the sentence suggests:

• one pepper
• one avocado

Also, die Paprika can be tricky because the form looks the same in singular and plural in some contexts. But in this sentence, singular is the most likely reading.

The dictionary form is würfeln.

The sentence uses the 1st person singular present tense:

• ich würfle = I dice

A quick pattern:

• ich würfle
• du würfelst
• er/sie/es würfelt
• wir würfeln

So if you look it up in a dictionary, search for würfeln, not würfle.
