Reggel gyors jegyzetet írok, mert később kevés időm lesz.

Here Reggel means in the morning or this morning, depending on context.

Hungarian often uses basic time words as adverbs without an extra ending:

• reggel = in the morning
• este = in the evening
• télen = in winter

So Reggel is functioning as a time expression by itself.

Because gyors describes the noun jegyzet.

• gyors jegyzet = a quick note
• gyorsan írok = I write quickly

So in this sentence, the meaning is that the note is quick/brief, not that the action of writing is fast.

Because it is the direct object of the verb írok.

Hungarian marks direct objects with the accusative ending -t. After some words, a linking vowel appears, so:

• jegyzet → jegyzetet

Here, jegyzetet means a note as the thing being written.

Hungarian has two main verb conjugations:

• indefinite conjugation
• definite conjugation

Here the object is indefinite: gyors jegyzetet = a quick note / some note, not the note.

So Hungarian uses the indefinite form:

• írok = I write / I am writing

You would use írom if the object were definite, for example:

• A jegyzetet írom. = I am writing the note.

Hungarian often leaves out egy when the object is nonspecific.

So:

• gyors jegyzetet írok = I’m writing a quick note
• egy gyors jegyzetet írok = also possible, but it can sound a bit more explicitly like one/a certain quick note

In many cases, English needs a, but Hungarian does not.

Mert means because.

It introduces the reason:

• Reggel gyors jegyzetet írok = I write a quick note in the morning
• mert később kevés időm lesz = because later I’ll have little time

So the second clause explains why the speaker is writing the note.

Később means later.

It comes from késő = late, with the comparative ending -bb:

• késő = late
• később = later

In this sentence, it works as a time adverb:

• később = later on

Hungarian usually does not use a separate verb meaning have the way English does.

Instead, it uses:

• the possessed noun
• a possessive suffix
• and usually van or lesz

So:

• időm van = I have time
• időm lesz = I will have time

Therefore:

• kevés időm lesz literally means little time-of-mine will be
• natural English: I’ll have little time

The -m shows my.

So:

• idő = time
• időm = my time

Hungarian often expresses possession with suffixes attached to the noun:

• könyv = book
• könyvem = my book
• autó = car
• autóm = my car

In this sentence, időm is part of the structure meaning I have time.

Lesz is the future form of van.

So:

• van = is
• lesz = will be

In possession structures, this gives:

• időm van = I have time
• időm lesz = I will have time

So kevés időm lesz means I will have little time.

Yes, Hungarian present tense can sometimes refer to the near future if the context makes the time clear.

Because the sentence begins with Reggel, the first clause could be understood as:

• I write a quick note in the morning
• I’m writing a quick note this morning
• I’ll write a quick note in the morning

The exact English translation depends on context. Hungarian often relies on time words instead of changing the verb form.

No, Hungarian word order is flexible, but different orders change emphasis.

This sentence has a natural, neutral flow:

• Reggel gyors jegyzetet írok, mert később kevés időm lesz.

That order gives:

• Reggel as the time setting
• gyors jegyzetet as the object
• írok as the verb

Other orders are possible, but they would highlight different parts of the sentence. Hungarian word order is strongly connected to focus and emphasis, not just grammar.
