Szerintem ez a kérdés egyszerű.

A very literal breakdown is:

• Szerintem = in my opinion / according to me
• ez a kérdés = this question
• egyszerű = simple

So the structure is basically:

In my opinion, this question simple.

In natural English, that becomes In my opinion, this question is simple or more idiomatically I think this question is simple.

Szerintem means in my opinion, according to me, or very often just I think in translation.

It is built from:

• szerint = according to
• -em = a 1st person singular ending meaning me / my side

So szerintem is literally something like according to me.

You will also see:

• szerinted = according to you / in your opinion
• szerinte = according to him/her / in his/her opinion
• szerintünk = in our opinion

So this is a very common Hungarian way to express opinion.

This is a very common Hungarian pattern.

In Hungarian, when a demonstrative like ez (this) or az (that) comes before a noun, the noun usually also takes the definite article:

• ez a kérdés = this question
• az a könyv = that book

So even though English says this question, Hungarian normally says literally this the question.

Also, Hungarian a here is not the English indefinite article a/an. It is the Hungarian definite article, meaning the.

One more useful detail:

• before a consonant: a
• before a vowel: az

So:

• ez a kérdés
• ez az ötlet

The form of the article depends on the following word.

Because Hungarian often leaves out the verb to be in the present tense, 3rd person when the predicate is a noun or adjective.

So:

• Ez a kérdés egyszerű. literally = This question simple. natural English = This question is simple.

This is normal Hungarian grammar.

But the verb appears in other situations, for example:

• past tense: Ez a kérdés egyszerű volt. = This question was simple.
• future-like expression: Ez a kérdés egyszerű lesz. = This question will be simple.

So the missing is is not an omission in casual speech; it is the standard rule here.

Kérdés is in the nominative form, which is the basic dictionary form.

There is no special ending on it here because it is the main noun in the statement: this question.

Compare:

• kérdés = question (basic form)
• kérdést = question as a direct object

For example:

• Ez a kérdés egyszerű. = This question is simple.
• Értem a kérdést. = I understand the question.

So in your sentence, kérdés stays in its base form.

Hungarian adjectives do not agree with nouns the way adjectives do in many Indo-European languages.

That means:

• no gender agreement
• usually no singular/plural agreement when directly before the noun

So:

• egyszerű kérdés = simple question
• egyszerű kérdések = simple questions

The adjective egyszerű stays the same.

In your sentence, egyszerű is a predicate adjective: it is saying what the question is like.

With a singular subject, the adjective stays in its base form:

• A kérdés egyszerű. = The question is simple.

With a plural subject, Hungarian often marks the predicate adjective as plural:

• A kérdések egyszerűek. = The questions are simple.

So in your sentence, egyszerű is unchanged because the subject is singular.

Usually egyszerű means simple, straightforward, or not complicated.

In some contexts, English might translate it as easy, especially if the idea is that something is uncomplicated. But the more direct Hungarian word for easy is often könnyű.

So:

• egyszerű kérdés = a simple question
• könnyű kérdés = an easy question

Sometimes those overlap in meaning, but not always.

In your sentence, simple is the safest and most literal meaning.

Yes. Hungarian word order is flexible, but changing it changes emphasis or information structure.

Your sentence:

• Szerintem ez a kérdés egyszerű.

is very natural and neutral. It sets up my opinion first, then gives the statement.

You could also say:

• Ez a kérdés szerintem egyszerű.

This is also natural. It highlights this question first, and szerintem sounds more like an inserted personal comment: This question, in my opinion, is simple.

So the meaning stays close, but the emphasis shifts.

As a learner, the original order is a good default.

A few important pronunciation points:

• sz sounds like English s
• s sounds like English sh
• é is a long e sound, roughly like ay in say but cleaner
• ű is a long front rounded vowel, like German ü if you know it

So:

• Szerintem: the sz is an s sound
• kérdés: the final s is sh, so it sounds roughly like KAYR-daysh
• egyszerű: the sz is s, and the final ű is the tricky ü-type sound

Also, Hungarian stress normally falls on the first syllable of each word:

• SZErintem
• EZ
• A
• KÉRdés
• EGYszerű

That first-syllable stress is very regular in Hungarian, which helps a lot once you get used to it.

Yes, you could, but the nuance is a little different.

• Szerintem = in my opinion
• Azt hiszem = I think / I believe

Both can work in English as I think, but:

• szerintem often sounds like giving an opinion or judgment
• azt hiszem can sound a bit more like a thought, assumption, or personal belief

So:

• Szerintem ez a kérdés egyszerű. = In my opinion, this question is simple.
• Azt hiszem, ez a kérdés egyszerű. = I think this question is simple.

Both are correct, but szerintem is especially natural for expressing an opinion about something.
