Az edzés ma kezdődik.

Hungarian has two forms of the definite article:

• a before a consonant sound
• az before a vowel sound

Since edzés begins with e, you say az edzés.

So:

• a könyv = the book
• az edzés = the training / the workout / the practice

Edzés is a noun meaning training, practice, or workout, depending on context.

It often refers to:

• sports practice
• exercise training
• a workout session

So in this sentence, it most likely refers to a specific training session or practice.

Kezdődik means begins or starts.

This is different from kezd:

• kezd = to start something
  
  • transitive: it takes an object
• kezdődik = to start / to begin
  
  • intransitive: the thing itself begins

Compare:

• A tanár kezdi az órát. = The teacher starts the lesson.
• Az óra kezdődik. = The lesson is starting / begins.

So in Az edzés ma kezdődik, the training itself is beginning, which is why kezdődik is the natural choice.

It is present tense, third person singular.

So literally, it is begins / is beginning.

Hungarian often uses the present tense for scheduled future events, especially when there is a time word like ma (today).

That means this sentence can naturally refer to something happening later today, even though the verb is formally present tense.

It is grammatically present, but in real use it often has a future-like meaning because of the context.

With ma (today), the sentence can mean:

• The training starts today
• Training begins today

So Hungarian uses the present form where English often prefers a present form with future meaning too, especially for schedules.

Ma means today, and its position helps show what information is important.

In Az edzés ma kezdődik, the structure sounds natural and neutral, with ma closely connected to the verb:

• Az edzés = topic, what we are talking about
• ma = time information
• kezdődik = the event

This often gives a sense like As for the training, it starts today.

Hungarian word order is flexible, but it is not random. Position often reflects focus, topic, and emphasis.

Yes, absolutely.

Ma kezdődik az edzés is also correct, but the emphasis changes.

A rough comparison:

• Az edzés ma kezdődik.
  = The training starts today.
  Neutral, talking about the training.

• Ma kezdődik az edzés.
  = Today is when the training starts.
  More emphasis on today.

Both are natural. Hungarian word order often changes according to what you want to highlight.

Using az suggests that this is a specific, identifiable training session — one that the speaker and listener both know about.

So az edzés is like:

• the training
• the practice
• the workout session

Without the article, edzés would sound more indefinite or more like a general concept, and in this sentence that is less natural.

No. Ma is an adverb, meaning today.

It does not have a case ending here. It simply gives time information.

Hungarian often uses simple adverbs of time like:

• ma = today
• holnap = tomorrow
• tegnap = yesterday

A simple pronunciation guide is:

Az edzés ma kezdődik
≈ awz ED-zhay-sh maw KEH-zdø-deek

A few helpful points:

• az: the z is pronounced
• edzés: dzs sounds like the j in jam
• é is a long ay-like vowel
• kezdődik:
  • e is like e in bed
  • ő is a rounded vowel that English does not really have
  • i is like ee in see

Stress in Hungarian is always on the first syllable of each word:

• AZ
• EDzés
• MA
• KEZdődik

Yes. They all come from the same basic idea of beginning / starting.

Related words include:

• kezd = start something
• kezdődik = begin, get started
• kezdés = beginning, starting
• kezdet = beginning, outset

Seeing these word families is very useful in Hungarian, because many words are built from the same root.
