Þó að ég sé svangur, borða ég bara eina brauðsneið.

Þó að means although / even though. It introduces a subordinate clause that sets up a contrast with the main clause.

So in:

Þó að ég sé svangur, borða ég bara eina brauðsneið.

the first part means Although I am hungry, and the second part gives the surprising or contrasting result: I only eat one slice of bread.

It is a very common way to express concession, like English although, even though, or despite the fact that.

This is one of the most important grammar points in the sentence.

After þó að, Icelandic often uses the subjunctive mood, especially in more careful or standard language. That is why you get:

• ég er = I am (indicative)
• ég sé = I be / I am in the subjunctive

So:

• Þó að ég er svangur may sometimes be heard in casual usage, but
• Þó að ég sé svangur is the standard grammatical form learners are usually taught.

Here, sé is the present subjunctive form of vera (to be).

Sé is the 1st person singular present subjunctive of vera (to be).

In this sentence:

• ég sé = I am in a subjunctive clause

Compare:

• ég er svangur = I am hungry
• þó að ég sé svangur = although I am hungry

So the meaning in English is still I am, but Icelandic marks the clause differently with the subjunctive.

In Icelandic, adjectives change form to match the noun or pronoun they describe in:

• gender
• number
• case

Here, svangur describes ég (I), specifically the speaker. Predicate adjectives after vera still agree with the subject.

So if the speaker is masculine, you get:

• ég er svangur = I am hungry

If the speaker is feminine, it would be:

• ég er svöng = I am hungry

So svangur tells you the speaker is male. Icelandic often reflects the speaker’s grammatical gender in this way.

This is due to the verb-second rule in Icelandic main clauses.

The sentence begins with a subordinate clause:

Þó að ég sé svangur

After that, the main clause starts:

borða ég bara eina brauðsneið

In Icelandic, when something other than the subject comes first in a main clause, the finite verb usually comes next. Since the subordinate clause occupies the first position, the main clause has inversion:

• normal order: Ég borða bara eina brauðsneið
• after an opening clause: Þó að ég sé svangur, borða ég bara eina brauðsneið

This is very similar to formal English word order in sentences like Although I’m hungry, I only eat one slice of bread, except Icelandic follows the verb-second rule much more consistently.

Bara usually means only, just, or sometimes simply, depending on context.

Here it means only:

• borða ég bara eina brauðsneið = I only eat one slice of bread

Its placement is natural in Icelandic. It usually comes before the word or phrase it semantically limits, or in a position that clearly affects the rest of the phrase.

In this sentence, bara limits the amount eaten: only one slice.

Because brauðsneið is the direct object of borða (to eat), it must be in the accusative case.

The noun brauðsneið is feminine, singular. The number einn (one) changes form to match it.

So:

• nominative: ein brauðsneið = one slice of bread
• accusative: eina brauðsneið = one slice of bread as an object

Since the sentence says I eat one slice of bread, the object is accusative:

• borða eina brauðsneið

Yes, brauðsneið is one compound word.

It is made from:

• brauð = bread
• sneið = slice

Together:

• brauðsneið = slice of bread

The -s- in the middle is a linking/genitive element, very common in Icelandic compounds.

This kind of compounding is extremely common in Icelandic, so it is useful to get used to seeing long words that are really built from smaller familiar parts.

Because the sentence is not talking about one bread, but one slice of bread.

The important noun is brauðsneið (slice of bread), not brauð by itself.

Also, brauð is neuter, while brauðsneið is feminine, so the form of one has to match brauðsneið:

• eitt brauð = one bread / one loaf of bread depending on context
• ein brauðsneið = one slice of bread (nominative)
• eina brauðsneið = one slice of bread (accusative)

Yes. Þótt is closely related and often means although / even though as well.

So these are both possible:

• Þó að ég sé svangur...
• Þótt ég sé svangur...

They are very similar in meaning. Learners will encounter both. In many contexts, they are interchangeable, though style and frequency can vary by speaker and text.

In standard writing, yes, a comma is normally used after the subordinate clause before the main clause:

Þó að ég sé svangur, borða ég bara eina brauðsneið.

This helps mark the boundary between:

• the subordinate clause: Þó að ég sé svangur
• the main clause: borða ég bara eina brauðsneið

So even if punctuation rules can vary a bit by style, this comma is normal and expected.

The main change would be the adjective svangur.

For a female speaker:

• Þó að ég sé svöng, borða ég bara eina brauðsneið.

Why?

Because the adjective must agree with the speaker’s gender:

• masculine: svangur
• feminine: svöng

The rest of the sentence stays the same.

Here are the main dictionary forms:

• þó að = although / even though
• ég = I
• vera = to be
  
  • sé is a form of vera
• svangur = hungry (masculine form listed as dictionary form)
• borða = to eat
• bara = only / just
• einn = one
• brauðsneið = slice of bread

This is useful because in Icelandic, the form you see in the sentence is often not the same as the dictionary form, especially for verbs, adjectives, and numbers.
