Valahányszor késedelmi díjat fizetek, javasolják, hogy ellenőrizzem a határidőt.

Valahányszor is a subordinating word meaning whenever or every time that. It introduces a time clause.

So:

• Valahányszor késedelmi díjat fizetek = Whenever I pay a late fee

It is more formal or literary than some everyday alternatives. In casual speech, learners may also meet:

• amikor csak
• minden alkalommal, amikor

But valahányszor is perfectly correct and elegant.

The -t ending marks the accusative case, which usually shows the direct object of the verb.

Here, the verb is fizetek = I pay, and what is being paid is the late fee:

• késedelmi díj = late fee
• késedelmi díjat = a/the late fee, as the object

So Hungarian marks the object directly on the noun, unlike English, which mostly relies on word order.

Késedelmi is an adjectival form meaning related to delay / late / overdue.

It comes from késedelem = delay. In Hungarian, nouns are often turned into adjective-like modifiers to describe another noun:

• késedelem = delay
• késedelmi díj = late fee / penalty fee

The word késedelmi does not take the accusative ending here because the case ending goes on the whole noun phrase, specifically on the final noun:

• késedelmi díjat

This is normal in Hungarian: modifiers usually stay unchanged, while the main noun gets the case ending.

Hungarian verbs have two main conjugations:

• indefinite
• definite

The indefinite form is used when the object is indefinite, nonspecific, or understood in a more general sense.

Here we have:

• fizetek = I pay

This works naturally with késedelmi díjat, which is presented as a general object, not a uniquely identified one.

If the sentence referred to a specific, known fee, Hungarian could use the definite conjugation in a different context. But here the general idea is whenever I pay a late fee, so fizetek is the expected choice.

Javasolják is they recommend / it is recommended.

Hungarian often leaves the subject unstated when it is general, unknown, or unimportant. So this can mean something like:

• they recommend
• people recommend
• it is recommended

In English, we often need to choose a subject or use a passive structure. Hungarian can simply use a 3rd person plural verb form without naming who they are.

So javasolják is a very common way to express an impersonal recommendation.

Because hogy introduces a subordinate clause.

The structure is:

• javasolják = they recommend
• hogy ellenőrizzem a határidőt = that I check the deadline

Hungarian normally separates such subordinate clauses with a comma, especially when a clause introduced by hogy follows the main clause.

So the comma is standard punctuation here.

Hogy usually means that when it introduces a clause.

Here it connects the main clause and the content of the recommendation:

• javasolják, hogy... = they recommend that...

This is a very common pattern in Hungarian.

Examples of similar structures:

• Azt mondják, hogy... = They say that...
• Szeretném, hogy... = I would like that...
• Javasolják, hogy... = They recommend that...

Ellenőrizzem is a subjunctive-like form used after verbs such as recommend, suggest, want, and similar expressions.

Compare:

• ellenőrzöm = I check / I am checking
• ellenőrizzem = that I check / for me to check

After javasolják, hogy..., Hungarian normally uses this form because the action is recommended, desired, or proposed rather than simply stated as a fact.

So:

• javasolják, hogy ellenőrizzem = they recommend that I check

This is one of the most important uses of the Hungarian subjunctive form.

It comes from the verb ellenőriz = to check / inspect.

The form ellenőrizzem contains:

• the verb stem
• subjunctive marker
• 1st person singular ending

So it means:

• that I check
• for me to check

You do not need to break it down every time, but it is useful to recognize that the -jem / -em type ending often appears in subordinate clauses after hogy when the meaning is suggestion, wish, command, or purpose.

Because it is the direct object of ellenőrizzem.

• határidő = deadline
• határidőt = the deadline, as the object

So in the clause:

• ellenőrizzem a határidőt

the thing being checked is the deadline, and that is why it takes the accusative -t.

Notice that the definite article a is also there:

• a határidőt = the deadline

Yes, Hungarian word order is flexible, but not random. It often reflects focus, emphasis, and information structure more than strict grammatical roles.

This sentence has a neutral, natural flow:

• Valahányszor késedelmi díjat fizetek, javasolják, hogy ellenőrizzem a határidőt.

It starts with the time clause, then gives the main statement, then the content of the recommendation.

Other word orders are possible if you want to emphasize something, but the given order is standard and easy to understand. For learners, it is best to read it as:

1. time/situation
2. main action
3. subordinate hogy clause

It sounds correct and somewhat formal or written, especially because of valahányszor and the impersonal javasolják.

More everyday Hungarian might use slightly different wording, for example with a more conversational time expression or a more direct subject. But the sentence itself is fully natural in formal writing, instructions, notices, or official communication.

So if you see or hear this structure, it is good Hungarian; it just leans a bit toward a more formal register.

Yes, that is a very useful way to learn it.

A common Hungarian pattern is:

• javasolják, hogy + subjunctive verb

Examples:

• Javasolják, hogy várjak. = They recommend that I wait.
• Javasolják, hogy menjünk korábban. = They recommend that we go earlier.
• Javasolják, hogy ellenőrizzem a határidőt. = They recommend that I check the deadline.

If you learn this pattern as a chunk, it becomes much easier to produce similar sentences.
