kono sakuhin ga suki desu.

This is one of the most common questions.

In Japanese, 好き is not a verb like English to like. It behaves more like an adjective, meaning something like liked or pleasant.

So the structure is closer to:

• この作品が好きです
• literally: As for me, this work is liked / pleasing

Because of that, the thing you like is often marked with が, not を.

Compare:

• 寿司が好きです。 = I like sushi.
• 猫が好きです。 = I like cats.

English uses a verb: I like this work.
Japanese uses a different pattern: This work is liked (by me).

No. 好き is not a verb.

It is usually treated as a na-adjective in modern Japanese grammar.

That is why you say:

• 好きです
• 好きな作品
• 好きじゃないです

and not a verb form such as 好きます.

This surprises English speakers because the sentence translates naturally with the verb like, but grammatically Japanese is using an adjective-like word.

です makes the sentence polite.

So:

• この作品が好きです。 = polite
• この作品が好き。 = casual

In this sentence, です is not doing the same job as English is in a full literal sense. It is mainly there to give the sentence a polite ending.

Yes, you can, but the nuance changes.

• この作品が好きです。
  This focuses on this work as the thing that is liked.

• この作品は好きです。
  This sets this work up as the topic, often with a contrastive feeling such as as for this work, I like it.

So が is very natural when simply stating what you like.
は can sound like you are contrasting it with something else, even if only slightly.

For example:

• この作品は好きですが、続編はあまり好きではありません。
  I like this work, but I do not really like the sequel.

Japanese often leaves out the subject when it is obvious from context.

So この作品が好きです usually means:

• I like this work
• or sometimes someone likes this work, depending on context

In normal conversation, if you are talking about your own opinion, I does not need to be said.

If you want to make it explicit, you could say:

• 私はこの作品が好きです。 = I like this work.

But in many situations, adding 私は is unnecessary.

この means this, and it must come directly before a noun.

So:

• この作品 = this work

You cannot use この by itself. It needs a noun after it.

Compare:

• この作品 = this work
• これ = this one / this

So if you want to say this work, you use この + noun.

作品 usually means a work or piece of work, especially something creative.

It can refer to things like:

• a novel
• a movie
• a painting
• a poem
• a game
• an artwork
• a creative production in general

So この作品が好きです is a natural sentence when talking about art, literature, film, or other creative works.

It sounds a bit more formal or broad than some more specific nouns. For example:

• この映画が好きです。 = I like this movie.
• この小説が好きです。 = I like this novel.
• この作品が好きです。 = I like this work/piece.

The spaces are usually just for learners.

Normal Japanese writing would be:

• この作品が好きです。

Japanese is not normally written with spaces between words the way English is. Textbooks and beginner materials sometimes add spaces to make the structure easier to see.

The casual version is:

• この作品が好き。

You simply drop です.

Depending on the situation, you might also hear:

• この作品、好き。

That version is even more conversational, with a pause after この作品.

To some extent, yes, because Japanese particles show the role of each word.

The standard order is:

• この作品が好きです。

This is the most natural basic form.

Japanese is more flexible than English, but not every rearrangement sounds equally natural. For beginners, it is best to keep the usual order:

noun + が + 好きです

So a good pattern to remember is:

• X が 好きです = I like X

Na-adjectives only take な when they directly modify a noun.

For example:

• 好きな作品 = a work that I like / favorite work

But when 好き is used as the main predicate of the sentence, you do not use な:

• この作品が好きです。

So:

• before a noun: 好きな + noun
• at the end of a sentence: 好きです

Yes, in theory it could, because Japanese often omits the subject.

The exact meaning depends on context.

For example:

• If you are answering a question about your preferences, it means I like this work.
• If you are describing another person and that is already clear from context, it could mean they like this work.

In real conversation, listeners usually understand the missing subject from the situation.

You can say:

• この作品が好きじゃないです。
• この作品が好きではありません。

Both mean I do not like this work.

The second version is more formal.

So:

• 好きです = like
• 好きじゃないです = do not like
• 好きではありません = do not like, more formal

You can say:

• この作品が好きですか。

That is the polite question form.

In casual speech:

• この作品が好き？

Remember that Japanese often omits you, so there is no need to say it unless you specifically want to.
