Jag fick nyss ett meddelande från henne.

Fick is the past tense of få, which usually means to get / to receive.

So:

• jag får = I get / I am getting
• jag fick = I got
• jag har fått = I have gotten / I have received

In Jag fick nyss ett meddelande från henne, fick tells you the action happened in the past: I got / received a message from her.

Swedish often uses få in everyday language where English might say get or receive.

• Jag fick ett brev = I got a letter / I received a letter
• Hon fick ett jobb = She got a job
• Vi fick hjälp = We got help

There is also motta for receive, but that is more formal. In normal conversation, få is much more natural.

Nyss means just now, a moment ago, or very recently.

So Jag fick nyss ett meddelande från henne means the message arrived a short time ago.

It is a very common adverb in spoken and written Swedish.

Compare:

• nyss = just now / moments ago
• precis = just, exactly, often also just now depending on context
• nyligen = recently, usually a bit less immediate than nyss

Yes, nyss can move, but the original version is very natural.

In a main clause, Swedish normally has the finite verb in second position, so:

• Jag = subject
• fick = finite verb
• nyss = adverb
• ett meddelande = object

This is a common pattern.

You may also hear:

• Jag fick ett meddelande nyss
• Nyss fick jag ett meddelande från henne

These are all possible, but they may shift emphasis slightly:

• Jag fick nyss... = neutral, very common
• Jag fick ett meddelande nyss = puts nyss a bit later, still natural
• Nyss fick jag... = emphasizes the time

Because meddelande is an ett-word in Swedish.

Swedish nouns have grammatical gender, and the two common indefinite articles are:

• en for common gender nouns
• ett for neuter nouns

So:

• ett meddelande = a message
• meddelandet = the message

This is something you usually just have to learn with each noun.

The -e is simply part of the noun itself: meddelande.

It is not being added because of the grammar in this sentence. The dictionary form is already meddelande.

This noun comes from a verb-related pattern and belongs to a group of words that often look similar, such as:

• ett meddelande = a message
• ett erbjudande = an offer
• ett erkännande = an acknowledgment / confession

So here, meddelande is just the normal singular indefinite form.

Because after a preposition like från (from), Swedish uses the object form of the pronoun.

Compare:

• hon = she
• henne = her

So:

• Hon skrev till mig = She wrote to me
• Jag fick ett meddelande från henne = I got a message from her

This is similar to English:

• she wrote
• from her

Usually, från henne is the natural choice here.

• från henne = from her, indicating the message came from her
• av henne often means by her, and is more commonly used for authorship, agency, or passive constructions

Examples:

• Ett brev från henne = a letter from her
• En bok av henne = a book by her
• Det skrevs av henne = It was written by her

So for a message that came from someone, från henne is the normal choice.

Yes. Meddelande is quite broad and can mean many kinds of message:

• a text message
• a direct message
• a voicemail
• a written message in an app
• a general message from someone

If Swedish wants to be more specific, it can use other words:

• ett sms = a text message
• ett mejl = an email
• ett röstmeddelande = a voice message

So ett meddelande is a general, flexible word.

Yes, absolutely. That is probably the most natural English translation in many contexts.

Because nyss means just now, English often uses just:

• Jag fick nyss ett meddelande från henne
  = I just got a message from her

Depending on context, you could also say:

• I just received a message from her
• I got a message from her a moment ago

It is neutral everyday Swedish.

Nothing in it is especially formal or especially slangy:

• Jag fick = normal
• nyss = common everyday word
• ett meddelande = neutral
• från henne = neutral

So you could say this in conversation, text messages, or normal writing without sounding strange.

Here are some useful comparisons:

• Jag får ett meddelande från henne.
  = I get / am getting a message from her

• Jag fick nyss ett meddelande från henne.
  = I just got a message from her

• Jag har fått ett meddelande från henne.
  = I have received / got a message from her

The original sentence uses the simple past (fick) together with nyss, which is very natural in Swedish. English often prefers the version with just got, but Swedish does not need the perfect here.
