Það verður auðveldara að skilja textann þegar framburðurinn er skýr.

Here það is a dummy subject, similar to English it in sentences like It is easy to understand the text.

It does not refer to a specific thing. Instead, it fills the subject position while the real idea is the infinitive phrase:

að skilja textann = to understand the text

So the structure is basically:

Það verður auðveldara ... = It will become easier ...

Verður is the present tense of verða, which often means become or can help express the future, like will be.

So:

• Það er auðvelt = It is easy
• Það verður auðveldara = It will be easier / It becomes easier

In this sentence, verður suggests a change or a future result: understanding the text gets easier when the pronunciation is clear.

Auðveldara is the comparative form of auðveldur = easy.

So the pattern is:

• auðvelt = easy
• auðveldara = easier

It appears in the neuter singular form because expressions like Það er auðvelt að... and Það verður auðveldara að... normally use the neuter singular adjective after dummy það.

So:

• Það er auðvelt að lesa. = It is easy to read.
• Það verður auðveldara að lesa. = It will be easier to read.

Here að is the infinitive marker, like English to.

So:

• skilja = understand
• að skilja = to understand

That whole phrase, að skilja textann, means to understand the text.

This is very common in Icelandic after adjectives such as:

• gaman að = fun to
• erfitt að = difficult to
• auðvelt að = easy to

Because textann is the definite accusative singular form of texti.

Here is the basic pattern:

• texti = a text / text (nominative singular)
• texta = text (accusative singular, indefinite)
• textann = the text (accusative singular, definite)

Since skilja takes a direct object, and the sentence means understand the text, Icelandic uses the accusative definite form:

að skilja textann

The ending -ann is the definite ending here.

Here þegar means when.

So:

þegar framburðurinn er skýr = when the pronunciation is clear

Be careful, because þegar can also mean already in other contexts. But in this sentence it is clearly a conjunction introducing a clause.

Framburðurinn means the pronunciation.

The base noun is:

framburður = pronunciation

And -inn is the definite article attached to the noun, so:

• framburður = pronunciation
• framburðurinn = the pronunciation

It is also in the nominative singular here because it is the subject of the clause:

framburðurinn er skýr = the pronunciation is clear

Because skýr has to agree with framburðurinn, which is masculine singular nominative.

The adjective skýr = clear changes form depending on gender, number, and case.

Here the subject is:

framburðurinn = masculine singular nominative

So the adjective must match:

framburðurinn er skýr

If the subject were neuter, you would get a neuter form such as skýrt instead.

This is normal in Icelandic.

After time words like þegar (when), Icelandic often uses the present tense to talk about a future situation, much like English does:

• when the pronunciation is clear
• not usually when the pronunciation will be clear

So:

Það verður auðveldara ... þegar framburðurinn er skýr

means something like:

It will be easier ... when the pronunciation is clear

That combination of a future idea in the main clause and present tense in the time clause is completely natural.

The sentence has two parts:

1. Það verður auðveldara að skilja textann
2. þegar framburðurinn er skýr

The first is the main clause. The second is a subordinate clause introduced by þegar.

A simple way to see it is:

• Það = dummy subject
• verður = verb
• auðveldara = predicate adjective
• að skilja textann = infinitive phrase
• þegar framburðurinn er skýr = time clause

So the sentence literally works as:

It will be easier to understand the text when the pronunciation is clear.

Yes, in terms of meaning, you can think of að skilja textann as the real content that the sentence is talking about.

Compare English:

It is easy to understand the text.

The word it is just a placeholder, and to understand the text carries the actual meaning.

The same idea applies here:

• það = placeholder
• að skilja textann = the meaningful action being discussed

So Icelandic often uses this pattern with það + adjective + að + infinitive.

These are two very important Icelandic letters:

• þ is like the th in thin
• ð is like the th in this

Examples from the sentence:

• Það: starts with þ, so the first sound is like thin
• verður: has ð, like the voiced th in this
• framburðurinn: also contains ð

One useful detail: ð is often softer than English speakers expect, especially at the end of a word, and sometimes it is barely heard.

Yes. Both are reasonable depending on how natural you want the English to sound.

• Það verður auðveldara... can be understood as It will be easier...
• It also carries the sense It becomes easier...

So verða often overlaps with both become and future be in English. In this sentence, the main idea is that clear pronunciation leads to easier understanding.
