Í yfirlitinu sé ég tvær afborganir og eina innborgun frá síðasta mánuði.

Yfirlitinu is the dative singular definite form of yfirlit.

Why dative? Because í takes:

• dative for location: in
• accusative for motion into something

Here the meaning is location, so í yfirlitinu means in the overview / in the statement.

Breakdown:

• yfirlit = overview, statement, summary
• yfirlitinu = the overview/statement, in the dative singular

So the ending -inu is basically showing the plus the correct case ending.

This is because Icelandic normally follows the V2 rule in main clauses: the finite verb tends to come in the second position.

Here, the sentence begins with Í yfirlitinu, so that first slot is already taken. The verb sé comes next, and then the subject ég follows:

• Í yfirlitinu sé ég ...

If you started with the subject instead, you would get:

• Ég sé tvær afborganir og eina innborgun í yfirlitinu.

Both are grammatical. The version with Í yfirlitinu first gives a little more emphasis to in the statement / overview.

Yes. Here sé is the 1st person singular present of að sjá (to see).

So:

• ég sé = I see

This verb is irregular, so the form does not look exactly like the infinitive sjá.

A useful mini-pattern:

• að sjá = to see
• ég sé = I see
• þú sérð = you see
• hann/hún sér = he/she sees

One thing that can confuse learners: sé can also be a form of vera in other contexts, but in this sentence it clearly means see, not be.

Because Icelandic numbers and number-like words agree with the noun in gender, number, and case.

Both afborganir and innborgun are feminine nouns, but:

• afborganir is plural
• innborgun is singular

So you get:

• tvær afborganir = two installments/repayments
• eina innborgun = one deposit

The forms are:

• tvær = feminine form of two
• eina = feminine accusative singular form of one

Yes. They are the direct objects of sé (I see), and að sjá normally takes the accusative.

So:

• sé ég tvær afborganir
• og eina innborgun

That is why the counting words also appear in accusative-compatible forms.

A quick breakdown:

• afborgun = nominative singular
• afborganir = accusative plural here
• innborgun = singular form; nominative and accusative singular look the same

They are both financial words, but they refer to different kinds of payments.

• afborgun = an installment or repayment, usually money paid off toward a debt or loan
• innborgun = a deposit or payment into an account

So in a banking or payment overview, these would be different transaction types.

Because frá always takes the dative.

So:

• mánuður = month
• mánuði = dative singular of mánuður

The adjective also has to match, so:

• síðasta mánuði = last month, in the dative after frá

So the whole phrase means:

• frá síðasta mánuði = from last month

It is the form that matches the noun phrase required here: dative singular masculine with mánuði.

In time expressions like last month, next year, and similar phrases, Icelandic often uses forms like:

• síðasta mánuði
• næsta ári

So even if the ending feels unexpected at first, síðasta mánuði is the normal expression for from last month after frá.

It can be a little ambiguous, just like in English.

Because frá síðasta mánuði comes right after eina innborgun, a reader may first connect it with the one deposit. But in context, it could also be understood more broadly.

If you want to make the meaning clearer, Icelandic can reposition the phrase:

• Í yfirlitinu frá síðasta mánuði sé ég tvær afborganir og eina innborgun.
  = In the overview from last month, I see...

That clearly makes from last month describe the overview.

Yes, to some extent. Icelandic allows different word orders, but the emphasis changes.

For example:

• Ég sé tvær afborganir og eina innborgun í yfirlitinu.

This is perfectly normal and may feel more straightforward to a learner.

The original:

• Í yfirlitinu sé ég tvær afborganir og eina innborgun ...

puts extra focus on in the overview / statement and follows the usual Icelandic V2 pattern.

So the meaning stays similar, but the information structure changes.

Here are the main nouns:

• yfirlit — neuter
• afborgun — feminine
• innborgun — feminine
• mánuður — masculine

This matters because Icelandic grammar depends heavily on gender and case. For example:

• feminine nouns help explain tvær and eina
• masculine mánuður helps explain síðasta mánuði
• neuter yfirlit helps explain yfirlitinu
