Uppsögnin kom í dag.

Uppsögnin consists of:

• uppsögn = a resignation, dismissal, termination notice, or cancellation notice, depending on context
• -in = the definite article the

So uppsögnin literally means the resignation / the notice / the termination.

A very important Icelandic feature is that the is usually attached to the end of the noun, instead of standing as a separate word like in English.

That is normal in Icelandic.

Instead of saying something like English the notice, Icelandic usually says:

• uppsögn = a notice / resignation
• uppsögnin = the notice / the resignation

This attached the is called the suffixed definite article.

So in this sentence, Icelandic does not need a separate word for the.

It is in the nominative singular.

Why?

Because uppsögnin is the subject of the sentence — it is the thing that came.

So the structure is:

• uppsögnin = subject, nominative singular
• kom = verb
• í dag = time expression, today

Since uppsögn is a feminine singular noun, the nominative definite form is uppsögnin.

Because kom is the past tense of koma (to come).

• kemur = comes / is coming
• kom = came

So:

• Uppsögnin kemur í dag = The notice is coming today / comes today
• Uppsögnin kom í dag = The notice came today

Even if English might sometimes use present perfect in similar situations, Icelandic here simply uses the past tense.

Because Icelandic verbs do not agree with the subject in gender.

Here, kom is just the 3rd person singular past form of koma, and it works for:

• hann kom = he came
• hún kom = she came
• það kom = it came

So even though uppsögnin is feminine, the verb stays kom.

Í dag means today.

It is a very common fixed expression:

• í = in
• dag = day

Historically and grammatically, this uses the noun dagur (day) in a case form after the preposition. But for a learner, the most useful thing is to remember í dag as a whole expression meaning today.

Similar expressions include:

• í morgun = this morning / in the morning
• í gær = yesterday
• á morgun = tomorrow

So í dag is best learned as a standard time phrase.

The word order here is very straightforward and natural:

• Uppsögnin = subject
• kom = verb
• í dag = time expression

So it follows a simple pattern similar to English:

The notice came today.

Icelandic can move elements around for emphasis, but the verb still obeys Icelandic word-order rules. For example, you might also see:

• Í dag kom uppsögnin.

That would put more emphasis on today.

But Uppsögnin kom í dag is perfectly normal and neutral.

Not always.

Uppsögn can refer to several related ideas, depending on context, such as:

• a resignation
• a dismissal
• a termination
• a cancellation notice
• a notice period / notice of ending something

So the exact English word depends on what is being talked about:

• a job
• a contract
• a subscription
• a lease
• etc.

That is why context matters a lot with this noun.

A rough pronunciation guide for an English speaker would be something like:

• uppsögnin ≈ UP-soeg-nin
• kom ≈ kohm
• í dag ≈ ee dahg

A few useful notes:

• ö does not exist in English exactly; it is somewhat like the vowel in French peur or German schön
• í is a long ee sound
• g in dag is pronounced, though not exactly like English g in all contexts

If you are learning pronunciation, it is better to listen to native audio, because Icelandic spelling and sound correspondences can be tricky at first.

The dictionary forms are:

• uppsögnin → uppsögn
• kom → koma
• í → í
• dag → dagur (in the expression í dag)

So if you wanted to look the words up, those are the forms you would usually search for.

The indefinite version would be:

Uppsögn kom í dag.

That means a resignation / a notice came today.

Compare:

• uppsögn = a resignation / a notice
• uppsögnin = the resignation / the notice

So the only difference is the attached definite article -in.
