Ég tek mína eigin glósubók með mér á fundinn.

Tek is the 1st person singular present tense of taka, meaning to take.

So:

• ég tek = I take
• þú tekur = you take
• hann/hún/það tekur = he/she/it takes

It is an irregular verb, so the stem changes from tak- to tek- in the present singular.

Because glósubók is the direct object of tek, and direct objects after taka are normally in the accusative.

Also, glósubók is feminine singular, so the possessive adjective minn has to agree with it in:

• gender
• number
• case

Here that gives:

• mína = feminine, singular, accusative

Compare:

• mín glósubók = my notebook, nominative
• mína glósubók = my notebook, accusative

Eigin means own.

So mína eigin glósubók means my own notebook. It adds emphasis: this is not just a notebook that belongs to me, but specifically my own one, not someone else’s.

Without eigin:

• mína glósubók = my notebook

With eigin:

• mína eigin glósubók = my own notebook

Yes. Eigin also agrees with the noun, just like mína does.

In mína eigin glósubók, it matches glósubók, which is:

• feminine
• singular
• accusative

The form eigin happens to be the correct agreeing form here.

So both mína and eigin are shaped by glósubók.

Because Icelandic normally does not use the definite article on a noun when a possessive comes before it.

So you get:

• mína eigin glósubók = my own notebook

not:

• mína eigin glósubókina

A useful pattern is:

• possessive before noun → usually no article
• possessive after noun → noun often does take the article

For example:

• mína glósubók
• glósubókina mína

Both can mean my notebook, but the structure is different.

Yes. That would be very natural Icelandic.

For example:

• Ég tek glósubókina mína með mér á fundinn.

That means essentially the same thing as the original sentence.

The difference is mainly one of structure and emphasis:

• mína eigin glósubók feels a bit more emphatic, especially because of eigin
• glósubókina mína is a very common everyday way to say my notebook

Because after the preposition með, the pronoun appears in an oblique case form, and in this expression the correct form is mér.

The pronoun forms are:

• ég = I
• mig = me
• mér = to me / me, depending on structure

In the phrase með mér, you must use mér.

So:

• með mér = with me

This is part of a very common pattern:

• taka eitthvað með mér = take something with me
• taka eitthvað með þér = take something with you
• taka eitthvað með sér = take something with him/her/oneself

Because á often changes meaning depending on case:

• á + accusative = movement toward / to
• á + dative = location / being at

Here the meaning is to the meeting, so Icelandic uses the accusative:

• á fundinn = to the meeting

Compare:

• á fundi = at a meeting
• á fundinum = at the meeting

So the sentence is talking about taking the notebook to the meeting, not already being at the meeting.

Fundinn is the accusative singular definite form of fundur, meaning meeting.

So:

• fundur = a meeting
• fundinn = the meeting, accusative

It is accusative because it follows á in a motion-toward sense, and it is definite because the speaker means a specific meeting.

Yes, very much so.

Icelandic often uses:

• taka
  • object + með mér/þér/sér

So:

• Ég tek bókina með mér = I take the book with me / I bring the book with me

This is a normal and idiomatic way to express the idea of bringing something along.

English often chooses between take and bring depending on point of view. Icelandic often simply uses taka in this kind of sentence and lets the context do the rest.

It is a compound noun:

• glósa = note, gloss
• bók = book

So glósubók is literally something like note-book.

A useful thing to know about Icelandic compounds is that the last part usually determines the gender. Since bók is feminine, glósubók is feminine too. That is why the sentence has:

• mína
• not minn
• and not mitt

The given word order is very natural and neutral:

• Ég tek mína eigin glósubók með mér á fundinn.

But Icelandic word order is somewhat flexible. You can move parts around for emphasis, especially because main clauses follow the verb-second pattern.

For example:

• Á fundinn tek ég mína eigin glósubók með mér.

That is still grammatical, but more marked.

For learners, the original order is a very good default:

• subject
• verb
• object
• prepositional phrases
