A kölcsönzési határidő ma lejár.

A is the definite article, so it means the.

Hungarian has two forms of the definite article:

• a before a consonant
• az before a vowel

Since kölcsönzési starts with a consonant sound, the sentence uses a.

It means something like borrowing due date, loan deadline, or simply due date in context.

You can break it down like this:

• kölcsönzés = borrowing, loaning
• kölcsönzési = related to borrowing
• határidő = deadline, due date

So the whole phrase is a noun phrase meaning the borrowing-related deadline.

Because -i is added to turn kölcsönzés into an adjective-like modifier.

So:

• kölcsönzés = borrowing
• kölcsönzési = borrowing-related

This is very common in Hungarian, especially in formal or administrative vocabulary.

A useful pattern to notice:

• olvasás → olvasási
• fizetés → fizetési
• kölcsönzés → kölcsönzési

Because határidő is a fixed compound noun, while kölcsönzési is a separate modifier.

• határidő = a compound word meaning deadline
• kölcsönzési határidő = adjective + noun, so it is written as two words

This is very typical in Hungarian:

• true compounds are often written as one word
• adjective + noun combinations are written separately

Here lejár means expires, runs out, or comes due.

In this sentence, it means that the deadline reaches its end today.

You will also see lejár with things like:

• tickets
• documents
• subscriptions
• deadlines
• loans

So it is a very natural verb for something that stops being valid or reaches its limit.

lejár is present tense, third person singular.

So it means:

• it expires
• he/she/it expires

Here the subject is a kölcsönzési határidő, so the meaning is the due date expires.

Hungarian does not need a separate word for it here, because the subject noun is already stated.

Because le- is a verbal prefix, and Hungarian verbal prefixes can move.

In a neutral sentence, the prefix usually stays attached:

• A kölcsönzési határidő ma lejár.

But if the verb is negated or something is strongly focused, the prefix often moves after the verb:

• A kölcsönzési határidő ma nem jár le.
• A kölcsönzési határidő MA jár le.

This is one of the most important patterns to learn with Hungarian prefix verbs.

ma means today, and time expressions often come before the verb in Hungarian.

So A kölcsönzési határidő ma lejár is a normal, natural word order:

• subject: a kölcsönzési határidő
• time word: ma
• verb: lejár

It sounds neutral and straightforward.

Yes, absolutely.

Ma lejár a kölcsönzési határidő is also natural. It puts today first as the topic of the sentence.

Both are fine:

• A kölcsönzési határidő ma lejár.
• Ma lejár a kölcsönzési határidő.

The difference is mainly about emphasis and information structure, not basic meaning.

Because Hungarian usually expresses this idea with the verb lejár when talking about deadlines, validity, or due dates.

So instead of saying the due date is today, Hungarian naturally says something closer to:

• the due date expires today

That is the idiomatic way to express the idea in this context.

In practice, it usually refers to the loan/borrowing process in a general sense, and the exact interpretation comes from context.

In a library context, kölcsönzési határidő is the date by which a borrowed item must be returned, so in natural English it is usually just the due date.

Hungarian does not always separate borrowing and lending in exactly the same way English does in this kind of phrase.
