A játékos lassan számolja a pontszámot.

A is the Hungarian definite article, meaning the.

So:

• a játékos = the player
• a pontszámot = the score (as the object)

Hungarian uses a before words that begin with a consonant, and az before words that begin with a vowel.

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

• dictionary form: pontszám
• accusative form: pontszámot

The core object marker is -t, but Hungarian often adds a linking vowel before it, so here you get -ot.

So:

• pontszám = score
• pontszámot = the score / score (as the thing being counted)

Because Hungarian verbs have two main conjugation patterns:

• indefinite conjugation
• definite conjugation

Here the object is definite: a pontszámot = the score, so Hungarian uses the definite verb form:

• számol = he/she counts
• számolja = he/she counts it / the specific thing

This is a very important Hungarian pattern. A definite object often triggers the definite conjugation.

It is:

• present tense
• third person singular
• definite conjugation

Its dictionary form is számol = to count.

So számolja means roughly he/she counts it or he/she is counting it, depending on context.

Because lassan is an adverb, while lassú is an adjective.

• lassú = slow
• lassan = slowly

In English, this is like the difference between:

• slow player
• counts slowly

So in the sentence, lassan modifies the verb számolja.

It can mean either, depending on context.

Hungarian often uses the simple present where English would choose either:

• counts
• is counting

So A játékos lassan számolja a pontszámot can mean:

• The player counts the score slowly
• The player is slowly counting the score

If you want to make the ongoing meaning more explicit, Hungarian often adds a word like éppen:

• A játékos éppen számolja a pontszámot. = The player is counting the score right now.

No, Hungarian word order is fairly flexible, but changing it often changes the emphasis.

This sentence is a natural, neutral way to say it:

• A játékos lassan számolja a pontszámot.

Here:

• A játékos is the topic
• lassan gives manner: slowly
• számolja is the verb
• a pontszámot is the object

You can move parts around, but then the sentence may sound more marked or emphasize something different.

Because Hungarian usually does not need a subject pronoun when the verb form already shows the person and number.

So számolja already tells you the subject is he/she/it in third person singular.

That means Hungarian can simply say:

• A játékos lassan számolja a pontszámot.

and does not need ő.

If ő is used, it often adds emphasis or contrast.

You would usually look up the base forms:

• játékos → already the base form
• lassan → look for lassú
• számolja → look for számol
• pontszámot → look for pontszám

This is very common in Hungarian: the form in the sentence often has endings attached, so you need to identify the stem.

A few helpful pronunciation points:

• Hungarian stress is usually on the first syllable of each word.
• j is pronounced like English y.
• sz is pronounced like English s.
• Hungarian s by itself is pronounced like English sh.

So:

• játékos sounds roughly like yaa-tay-kosh
• számolja sounds roughly like saa-mol-ya
• pontszámot sounds roughly like pont-saa-mot

Also, the accents matter:

• á is a long vowel
• é is a long vowel too

It breaks down like this:

• A játékos = the player
• lassan = slowly
• számolja = counts / is counting it
• a pontszámot = the score

So the structure is basically:

subject + adverb + verb + object

That is a very useful way to read beginner Hungarian sentences.
