Quina opinió tens sobre aquest article?

Quina means what or more literally which, and it agrees with opinió, which is a feminine singular noun.

So:

• quin = masculine singular
• quina = feminine singular
• quins = masculine plural
• quines = feminine plural

Because opinió is feminine singular, Catalan uses quina opinió.

In Catalan, què and quin/quina are used differently.

• què = what, used on its own
• quin/quina = which/what kind of, used before a noun

Since opinió is a noun, Catalan uses quina before it:

• Quina opinió tens...? = What opinion do you have...?
• Què penses...? = What do you think...?

English often uses what in both cases, but Catalan makes a distinction here.

Tens is the 2nd person singular form of tenir, meaning to have.

• jo tinc = I have
• tu tens = you have
• ell/ella té = he/she has

So Quina opinió tens...? literally means What opinion do you have...?

This sounds natural in Catalan, even though English would more often say What do you think...?

It is informal singular, because it uses tens, the form for tu.

If you wanted to address someone formally, you would usually say:

• Quina opinió té sobre aquest article?

Here té is the vostè form.

So:

• tens = informal you
• té = formal you

This is normal Catalan question word order.

A common pattern is:

Question word + noun + verb + rest

So:

• Quina opinió = what opinion
• tens = do you have
• sobre aquest article = about this article

Unlike English, Catalan does not need do in questions here.
English says What opinion do you have...?, but Catalan simply says Quina opinió tens...?

Sobre here means about or regarding.

So:

• sobre aquest article = about this article

It is a very common preposition in Catalan when talking about a topic:

• un llibre sobre història = a book about history
• parlar sobre política = to talk about politics

In everyday speech, other structures are also possible, but sobre is perfectly natural here.

Aquest means this and must agree with the noun it describes.

Since article is masculine singular, Catalan uses aquest.

Here is the pattern:

• aquest = this, masculine singular
• aquesta = this, feminine singular
• aquests = these, masculine plural
• aquestes = these, feminine plural

Examples:

• aquest article = this article
• aquesta revista = this magazine

Yes, in this context article means article, as in a newspaper, magazine, or online article.

Be aware that Catalan article can also mean grammatical article in grammar discussions, just like English article.

In this sentence, though, it clearly means a written piece.

Opinió is pronounced roughly like oh-pee-nee-O, with the stress on the final syllable.

The written accent ó shows where the stress falls. Without the accent, the stress pattern would be different.

A rough breakdown:

• o-pi-ni-Ó

The accent is important because Catalan spelling often marks irregular stress.

Yes. This sentence is correct, but many speakers would also say:

• Què en penses d'aquest article?

That means What do you think of this article?

Both are natural, but they feel slightly different:

• Quina opinió tens sobre aquest article? = a bit more explicit, somewhat more formal or careful
• Què en penses d'aquest article? = very common and conversational

So the original sentence is good Catalan, but it is useful to know the alternative too.

You can translate it literally as:

• What opinion do you have about this article?

That is understandable English, but the most natural English version is usually:

• What do you think about this article?
• What’s your opinion on this article?

So the Catalan structure is slightly closer to What opinion do you have...?, even though English often prefers a different phrasing.

Catalan does not need an article here because quina already introduces the noun.

Compare:

• quina opinió = what opinion
• not quina l'opinió

This is similar to English, where you say what opinion, not what the opinion.

So quina is doing the job of introducing the noun phrase.

A rough pronunciation guide is:

KEE-nuh oh-pee-nee-O tens SOH-bruh ah-KEST ar-TEE-kluh?

A few notes:

• Quina sounds roughly like KEE-nuh
• tens has a short e
• aquest ends with a clear t
• article is not pronounced exactly like English article

Pronunciation varies somewhat by dialect, but this approximation is good enough for a learner to start with.
