Ég drekk morgunkaffi í eldhúsinu áður en ég fer út.

Because drekk is the 1st person singular present tense form of the verb að drekka (to drink).

• að drekka = to drink
• ég drekk = I drink

So Icelandic verbs change depending on the subject, just like I am vs. we are in English.

A few present-tense forms of drekka:

• ég drekk = I drink
• þú drekkur = you drink
• hann/hún/það drekkur = he/she/it drinks
• við drekkum = we drink

So in this sentence, Ég drekk is simply I drink.

Morgunkaffi is a compound noun:

• morgun = morning
• kaffi = coffee

So morgunkaffi literally means morning coffee.

Icelandic very often combines words into a single compound where English might use two words. This is extremely common and natural in Icelandic.

Other examples of the same pattern:

• morgunmatur = breakfast, literally morning food
• eldhúsborð = kitchen table
• barnabók = children’s book

So drekk morgunkaffi means drink morning coffee.

Because Icelandic often leaves out possessives like my, your, etc. when the meaning is obvious from context.

So instead of saying:

• Ég drekk morgunkaffið mitt = I drink my morning coffee

Icelandic will often simply say:

• Ég drekk morgunkaffi = I drink morning coffee

This sounds natural when you are talking generally about your usual coffee or your coffee in that situation.

Using mitt is possible, but it would sound more explicit or emphatic.

Because eldhúsinu is the definite form: the kitchen.

• eldhús = kitchen
• eldhúsið = the kitchen
• eldhúsinu = in the kitchen / to the kitchen, depending on case and context

Icelandic usually puts the at the end of the noun instead of using a separate word like English the.

So:

• í eldhúsi = in a kitchen
• í eldhúsinu = in the kitchen

In your sentence, the meaning is specifically in the kitchen, so the definite form is used.

Because after í, Icelandic uses different cases depending on whether you mean:

• location = where something is
• movement = where something is going

Here, the sentence means in the kitchen as a location, so í takes the dative.

The noun is:

• eldhús = kitchen
• definite singular dative = eldhúsinu

So:

• í eldhúsinu = in the kitchen

This is an important pattern:

• í + dative = in/inside somewhere, staying there
• í + accusative = into somewhere, moving into it

Compare:

• Ég er í eldhúsinu. = I am in the kitchen.
• Ég fer í eldhúsið. = I go into the kitchen.

Áður en means before when it introduces a clause.

In this sentence:

• áður en ég fer út = before I go out

You can think of it as a fixed expression meaning before + a full clause.

Examples:

• áður en ég fer = before I go
• áður en þú byrjar = before you begin
• áður en við borðum = before we eat

So in your sentence:

• Ég drekk morgunkaffi í eldhúsinu áður en ég fer út.
• I drink morning coffee in the kitchen before I go out.

Because áður en introduces a new clause, and that clause needs its own subject.

So the sentence has two parts:

1. Ég drekk morgunkaffi í eldhúsinu
   = I drink morning coffee in the kitchen

2. áður en ég fer út
   = before I go out

In English, we can sometimes shorten this kind of thing:

• before going out

But Icelandic often uses a full clause with subject + verb:

• áður en ég fer út = before I go out

So the second ég is completely normal and necessary here.

Because fer is the 1st person singular present tense of að fara (to go).

• að fara = to go
• ég fer = I go

This verb changes quite a bit, so it is one you simply have to learn:

• ég fer = I go
• þú ferð = you go
• hann/hún/það fer = he/she/it goes
• við förum = we go

So:

• áður en ég fer út = before I go out

Út means out.

In this sentence, it works with fer:

• ég fer út = I go out

This is very similar to English. It is an adverb or directional particle showing movement outward.

Other examples:

• Komdu út. = Come out.
• Hann hleypur út. = He runs out.
• Við förum út í kvöld. = We are going out tonight.

So fer út is a very common everyday expression.

Because Icelandic has verb-second (V2) word order in many main clauses, but subordinate clauses usually do not follow the same verb-second pattern.

Main clause:

• Ég drekk morgunkaffi
  subject + verb

Subordinate clause after áður en:

• ég fer út
  subject + verb

That is the normal order here.

A useful contrast:

• Main clause: Nú fer ég út. = Now I’m going out.
  Here the verb comes early because of V2.
• Subordinate clause: áður en ég fer út = before I go out
  Here the subject stays before the verb.

So the word order in your sentence is exactly what you should expect.

No. That would be incorrect.

After áður en, you need a normal subordinate clause, so the subject must come before the verb:

• áður en ég fer út = correct
• áður en fer ég út = incorrect

This is one of those places where remembering main clause vs. subordinate clause is very helpful.

It can be either, depending on context.

The present tense in Icelandic, like in English, can express:

1. A habitual action

   • Ég drekk morgunkaffi... = I drink morning coffee...
   • This could mean it is part of my routine.

2. A present or near-present action

   • In the right context, it could also mean I am drinking morning coffee...

In this full sentence, many learners would naturally read it as a habitual routine:

• I drink morning coffee in the kitchen before I go out.

But context always matters.

Yes, a few things may stand out to English speakers:

• ég
  The é is not like English short e. It is more like yeh at the start, so ég sounds roughly like yeg.

• drekk
  The kk is pronounced as a strong doubled consonant. Icelandic often makes double consonants very noticeable.

• eldhúsinu
  This word has several syllables: eld-hú-si-nu.
  The ú is a long vowel sound, and the stress is normally on the first syllable: ELD-húsinu.

Also, Icelandic always marks vowel length and quality carefully, so the accent marks matter:

• á, é, í, ó, ú, ý are not optional spelling decorations; they indicate different vowel sounds.

Because Icelandic usually adds the definite article to the end of the noun instead of using a separate word.

For example:

• eldhús = kitchen
• eldhúsið = the kitchen

And when the noun changes case, the article changes with it:

• eldhúsið = the kitchen
• eldhúsinu = in the kitchen / to the kitchen in certain grammatical contexts

This is why you see eldhúsinu instead of something like the kitchen with a separate article.

Yes, you can, but the meaning changes slightly.

• áður en ég fer út = before I go out
• áður en ég fer = before I leave / before I go

Without út, the sentence is more general. With út, it specifically means out.

So if the idea is that the person drinks coffee before going outside or heading out, út is the better choice.
