Við æfum okkur daglega til að bæta framburðinn.

Because Icelandic verbs change form to match the subject.

• að æfa = to practice / to train
• við = we
• present tense with við takes -um here: við æfum

So Við æfum means we practice.

Here okkur is a reflexive pronoun, meaning the action is directed back at the subject.

• okkur = us / ourselves
• að æfa sig = to practice oneself / to train oneself

So Við æfum okkur is literally something like We practice ourselves, but in natural English you would usually just say We practice or We train.

In this sentence, okkur is in the accusative, because it is the direct object of æfa.

Daglega is an adverb, meaning daily or every day.

It comes from the adjective daglegur = daily.

Compare:

• dagleg æfing = a daily exercise/practice session
• við æfum daglega = we practice daily

So here it tells you how often the action happens.

Til að means to or in order to and introduces a purpose.

So:

• Við æfum okkur daglega = We practice daily
• til að bæta framburðinn = in order to improve the pronunciation

This is a very common Icelandic pattern:

• til að + infinitive

For example:

• Ég les til að læra. = I read to learn.
• Við æfum okkur til að verða betri. = We practice to become better.

Because after til að, Icelandic normally uses the infinitive.

So:

• að bæta = to improve
• til að bæta = to improve / in order to improve

The only fully conjugated verb in this sentence is æfum. Everything after til að gives the purpose of that action.

Because framburðinn is the definite accusative singular form.

The basic dictionary form is:

• framburður = pronunciation

But in the sentence it is the object of bæta, so it appears in the accusative. It is also definite, meaning the pronunciation.

So the form changes like this:

• nominative indefinite: framburður
• accusative definite: framburðinn

This kind of change is very normal in Icelandic, where nouns change for both case and definiteness.

Icelandic often uses a definite noun where English would prefer a possessive, especially when the owner is obvious from context.

So bæta framburðinn can naturally mean:

• improve the pronunciation
• improve our pronunciation

Since the subject is we, it is easy to understand whose pronunciation is being discussed.

If you really wanted to make the possession explicit, you could say something like framburðinn okkar, but that is less necessary here.

The given order is very natural and neutral:

• Við æfum okkur daglega til að bæta framburðinn.

But Icelandic word order is somewhat flexible. For example, you could move daglega to the front:

• Daglega æfum við okkur til að bæta framburðinn.

When something is moved to the front in a main clause, Icelandic usually keeps the finite verb in second position. That is an important pattern in Icelandic word order.

So the original sentence is not the only possible order, but it is a very standard one.

Yes:

• Við = we
• æfum = practice
• okkur = ourselves / us
• daglega = daily
• til að = to / in order to
• bæta = improve
• framburðinn = the pronunciation

A very literal version would be:

• We practice ourselves daily in order to improve the pronunciation.

A natural English version is:

• We practice every day to improve our pronunciation.
