Ma egyetlen futó regisztrál.

Ma means today.

It often appears near the beginning of the sentence because Hungarian commonly puts the time expression early, especially when it sets the scene for the whole statement.

So:

• Ma egyetlen futó regisztrál. = Today, a single runner registers / is registering.

This is natural Hungarian word order, but ma could appear elsewhere too if the speaker wanted a different emphasis.

Not quite.

• egy = one / a
• egyetlen = a single, only one, sometimes not a single in negative contexts

In this sentence, egyetlen futó means a single runner or only one runner.

So egyetlen is stronger and more emphatic than plain egy. It highlights that the number is very small: just one.

In Hungarian, you often do not use an article when a noun phrase already has a quantifying word like egy, két, sok, or egyetlen.

So:

• egyetlen futó = a single runner
• not az egyetlen futó here

Be careful, though:

• egyetlen futó = a single runner / only one runner
• az egyetlen futó = the only runner

That little article changes the meaning a lot.

Here it means one single runner or only one runner, not necessarily the only runner in existence.

If you wanted the only runner, Hungarian would normally use:

• az egyetlen futó

So the sentence as written is about the number registering today: only one runner is doing so.

Yes. Futó comes from fut = to run, but here futó is being used as a noun, meaning runner.

Hungarian often uses forms like this as nouns:

• fut = run
• futó = runner / running one

So egyetlen futó simply means a single runner.

Regisztrál is the 3rd person singular present tense form of the verb regisztrál = to register.

So it means:

• he/she registers
• a runner registers
• depending on context, it can also be understood as is registering

Because the subject is egyetlen futó = a single runner, the verb must be singular:

• futó regisztrál = the runner registers / is registering

It is indefinite conjugation.

Hungarian uses two main verb conjugation patterns:

• indefinite: when there is no definite object
• definite: when there is a definite object

Here, regisztrál has no object at all. The sentence just says that the runner registers. Since there is no definite object, the indefinite form is used.

That is why you get:

• regisztrál

rather than a definite-conjugation form.

Hungarian word order is much more flexible than English word order. It is not only about grammar; it is also about focus and information structure.

In Ma egyetlen futó regisztrál, the order sounds neutral and natural: first the time, then the subject, then the verb.

But other orders are possible, with slightly different emphasis, for example:

• Ma regisztrál egyetlen futó.
• Egyetlen futó regisztrál ma.

These versions may shift the focus a bit, but the basic meaning stays similar.

So the verb being last is completely normal here.

Grammatically, it is present tense.

However, Hungarian present tense can sometimes be used for a planned near-future event, especially if a time word is present.

So depending on context, Ma egyetlen futó regisztrál could mean:

• Today, a single runner is registering
• Today, only one runner registers
• sometimes even Today, only one runner will register

The exact English translation depends on the situation.

Yes, egyetlen can appear in expressions meaning not a single, but then Hungarian normally needs a negative element too.

For example:

• Ma egyetlen futó sem regisztrál. = Today not a single runner registers.

The word sem is important there.

Without that negative marking, egyetlen futó in this sentence is understood positively as:

• a single runner
• only one runner

So Ma egyetlen futó regisztrál does not mean Not a single runner registers today.

Yes, that is a very good translation.

Other natural translations include:

• Today, only one runner registers.
• Today, a single runner registers.
• Only one runner is registering today.

The best English version depends on the context and style, but Only one runner registers today matches the Hungarian very well.
