Elolvasom a hozzászólást.

Because el- is a verbal prefix attached to olvas (to read).

• olvas = read
• elolvas = read through, read completely

In Hungarian, these prefixes are often written together with the verb when nothing pulls them apart. So:

• Elolvasom = I read it / I will read it through / I’ll finish reading it

The prefix can separate in other sentence types, for example:

• Nem olvasom el. = I’m not reading it / I won’t read it through.

So in your sentence, it is one word because that is the normal neutral form.

Here el- usually gives the idea of completion or reading something through to the end.

Compare:

• olvasom = I am reading it / I read it
• elolvasom = I read it through / I’ll read it completely / I finish reading it

With actions like reading, writing, eating, etc., prefixes often make the verb feel more bounded or completed.

So Elolvasom a hozzászólást suggests not just the activity of reading, but the whole comment being read.

The -om ending shows:

• 1st person singular: I
• definite conjugation

Hungarian has two main verb conjugations:

1. indefinite conjugation
2. definite conjugation

You use the definite conjugation when the verb has a specific, definite object, such as:

• a hozzászólást = the comment

So:

• olvasok = I read / I am reading (indefinite, no specific object)
• olvasom = I read it / I am reading it (definite, a specific object)

That is why the sentence uses elolvasom, not elolvasok.

A is the Hungarian definite article, meaning the.

• a hozzászólás = the comment
• egy hozzászólás = a comment

Since the sentence refers to a specific comment, Hungarian uses a.

Note that Hungarian has two forms of the:

• a
• az

Which one is used depends on the following sound. Before a consonant, you usually get a:

• a hozzászólás

Before a vowel, you usually get az.

Because it is the direct object of the verb, so it takes the accusative ending -t.

• hozzászólás = comment / comment-post
• hozzászólást = comment as the thing being read

So:

• Elolvasom a hozzászólást. = I read the comment / I’ll read the comment through.

This -t is one of the most common Hungarian case endings.

Hozzászólás usually means something like:

• comment
• reply
• post
• contribution to a discussion

Its exact translation depends on context.

For example, online it often means:

• a forum post
• a comment under an article or video
• a reply in a discussion

So a hozzászólást could be translated in natural English as:

• the comment
• the post
• the reply

Formally, it is present tense in Hungarian, but in real use it can often refer to the future too, depending on context.

So Elolvasom a hozzászólást can mean things like:

• I’m reading the comment
• I’ll read the comment
• I’ll read through the comment

With a verb like elolvasom, English often uses the future because the completed meaning sounds natural that way.

Hungarian often uses the present tense for future meaning when the context makes it clear.

Because Hungarian usually does not need the subject pronoun when the verb ending already shows who the subject is.

• elolvasom already means I read it / I will read it

So én is optional.

You would add én mainly for emphasis or contrast:

• Én olvasom el a hozzászólást. = I am the one who will read the comment.

In a neutral sentence, leaving out én is completely normal.

Yes. Hungarian word order is flexible, and moving parts of the sentence changes the focus or emphasis, not just style.

• Elolvasom a hozzászólást. = neutral
• A hozzászólást elolvasom. = The comment, I’ll read (it).

The second version gives more prominence to a hozzászólást.

So both are possible, but the original sentence is the most neutral everyday order.

Yes. In Hungarian, the definite verb ending already suggests a definite object, so Elolvasom can mean:

• I’ll read it
• I’m reading it through
• I’ll read that

The object can be omitted if it is understood from context.

That is one useful thing about the definite conjugation: it often lets Hungarian leave out it when English would normally include it.

Then the verb would normally use the indefinite conjugation.

Compare:

• Elolvasom a hozzászólást. = I’ll read the comment.
  definite object → -om

• Elolvasok egy hozzászólást. = I’ll read a comment.
  indefinite object → -ok

This is an important Hungarian pattern:

• definite object → definite verb form
• indefinite object or no specific object → indefinite verb form

Because the article and the case ending do different jobs.

• a marks definiteness = the
• -t marks the accusative = the direct object

So both are needed:

• a hozzászólást = the comment as the thing being acted on

Hungarian often stacks this kind of information:

• article for definiteness
• noun ending for grammatical role

That is perfectly normal in the language.
