Bless, og takk fyrir í dag.

Bless is a very common Icelandic way to say bye. It is informal and friendly, and you can use it in everyday situations with friends, classmates, coworkers, shop staff, and so on.

In this sentence, it works just like an English farewell at the start of leaving:

• Bless = Bye

It can also appear as bless bless, which sounds a bit like bye-bye.

It is mostly informal to neutral everyday speech. It is extremely common and natural in daily Icelandic.

If you want to sound more formal, Icelandic also has other ways to say goodbye, but bless is the standard casual choice and is not rude. You will hear it very often.

Literally, the parts are:

• takk = thanks
• fyrir = for
• í dag = today

So word-for-word it is something like thanks for today.

In natural English, this usually means:

• Thanks for today
• Thanks for your time today
• Thanks for today’s lesson / meeting / visit / company

It is often said when parting after spending time together.

In Icelandic, takk fyrir is the normal pattern for saying thanks for ... something.

So you often get:

• Takk fyrir hjálpina = Thanks for the help
• Takk fyrir mig = Thanks for having me
• Takk fyrir í dag = Thanks for today

For an English speaker, it helps to learn takk fyrir as a set phrase.

Because the whole phrase is built as takk fyrir + what you are thanking someone for.

Here, what you are thanking them for is í dag — basically today / today’s time together.

So the structure is:

• takk fyrir
  • í dag

Even though í dag often just means today, in this expression it means something more like for today’s interaction.

You would say this when leaving after some shared activity or time together. For example:

• after a lesson
• after a meeting
• after visiting someone
• after work
• after a phone call or conversation that had some real substance

It sounds warm and polite, because you are both saying goodbye and thanking the other person for the time spent.

The comma separates two short farewell expressions:

• Bless
• og takk fyrir í dag

So it is like saying:

• Bye, and thanks for today.

In speech, there is usually a little pause there. The comma helps show that.

A rough learner-friendly pronunciation is:

bless, og tahk fuh-rir ee daug

A few notes:

• Bless sounds close to English bless, but shorter and crisper.
• og is often pronounced more like ok in everyday speech.
• takk has a clear k sound at the end.
• fyrir is often pronounced quickly, something like fuh-rir or fi-rir, depending on speech.
• dag in í dag does not sound exactly like English day.

If you want to sound natural, the rhythm matters a lot: Bless, og takk fyrir í dag.

Yes, it can be said to either one person or a group.

That is one useful thing about this sentence: nothing in it changes depending on whether you are speaking to one person or many. It works in both cases.

No. It is capitalized here only because it is the first word of the sentence.

In the middle of a sentence, it would normally be written bless.

Yes, very natural. It sounds like something a real speaker might easily say when leaving.

It combines:

• a common goodbye (Bless)
• a polite closing thanks (takk fyrir í dag)

So it is a very everyday, useful sentence to learn.
