Þvottakarfan er full, svo ég þarf að þvo aftur í kvöld.

The -n at the end is the suffixed definite article in Icelandic.

• þvottakarfa = a laundry basket
• þvottakarfan = the laundry basket

Icelandic usually adds the to the end of the noun instead of using a separate word like English does.

Here, þvottakarfan is also in the nominative singular, because it is the subject of the sentence.

Þvottakarfa is a feminine noun.

That matters because adjectives in Icelandic often agree with the noun in gender, number, and case. So when the sentence says the basket is full, the adjective has to match þvottakarfan.

That is why the sentence has:

• þvottakarfan — feminine singular definite noun
• full — feminine singular form of the adjective fullur (full)

Because the adjective must agree with þvottakarfan, which is feminine singular.

The basic forms are:

• fullur = masculine
• full = feminine
• fullt = neuter

So:

• Bíllinn er fullur = The car is full (masculine)
• Karfan er full = The basket is full (feminine)
• Glasið er fullt = The glass is full (neuter)

Even though full comes after er, it still agrees with the noun.

Here svo means so, therefore, or as a result.

It connects the two clauses:

• Þvottakarfan er full = The laundry basket is full
• svo ég þarf að þvo aftur í kvöld = so I need to wash again tonight

In other contexts, svo can also mean things like then, thus, or appear in other idiomatic expressions, but in this sentence it is simply a conjunction meaning so.

Because þvo is in the infinitive form, and after þurfa (to need) Icelandic normally uses að + infinitive.

So:

• ég þarf = I need
• að þvo = to wash

Together:

• ég þarf að þvo = I need to wash

This is very similar to English need to wash, except Icelandic uses the infinitive marker að.

Þarf is the present tense form of the verb þurfa (to need), here used with ég.

So:

• að þurfa = to need
• ég þarf = I need

This is just the normal present-tense verb form for I in this sentence.

Because after þarf you need the infinitive: að þvo.

The verb þvo means to wash. In this sentence it refers naturally to washing clothes / doing laundry, because the subject is a full laundry basket.

So although the literal wording is to wash, the natural meaning in context is often to do the laundry or to wash clothes.

No. Þvo is the general verb to wash.

It can be used for different things depending on context, for example:

• þvo föt = wash clothes
• þvo bílinn = wash the car
• þvo hárið = wash the hair

In this sentence, because of þvottakarfan (the laundry basket), the meaning is clearly about laundry.

Here aftur means again.

So:

• að þvo aftur = to wash again / do laundry again

In other contexts, aftur can also mean back, depending on the sentence. But here again is the right meaning.

Í kvöld means tonight or more literally this evening.

• kvöld = evening
• í kvöld = tonight / in the evening

Icelandic often uses prepositional time expressions where English may use a single adverb like tonight.

So even though English says tonight, Icelandic says something more like in evening.

Yes, this is something learners often notice.

The sentence has:

• svo ég þarf að þvo...

This is normal. After svo meaning so, you often get regular clause word order with the subject first:

• svo ég þarf... = so I need...

Icelandic word order can be more flexible than English, but this sentence is straightforward and natural.

The comma separates the two main parts of the sentence:

1. Þvottakarfan er full
2. svo ég þarf að þvo aftur í kvöld

This is similar to English punctuation in a sentence like:

• The laundry basket is full, so I need to wash again tonight.

So the comma helps show the pause and the relationship between the two clauses.

Þ / þ is pronounced like the th in think, not like the th in this.

So Þvottakarfan starts with that voiceless th sound.

A rough pronunciation guide for the beginning is:

• Þv- ≈ thv-

English speakers often find þv a bit awkward at first, but it gets easier with practice.

Yes. Icelandic makes a lot of compound nouns.

Þvottakarfa is made from:

• þvottur = washing / laundry
• karfa = basket

So þvottakarfa literally means something like laundry-basket.

Compound words are extremely common in Icelandic, so recognizing the parts can really help with vocabulary.

Yes, that is a very natural way to understand it.

The Icelandic wording is literally closer to:

• The laundry basket is full, so I need to wash again tonight

But in everyday English, depending on context, you could express the same idea as:

• I have to do laundry again tonight
• I need to do another load of laundry tonight

So the exact English wording can vary, even though the Icelandic sentence stays the same.
