kore ha kanengomi desu.

It is usually read かねんごみ.

• 可燃 = かねん = combustible / burnable
• ごみ = garbage / trash

So the whole noun means burnable trash or combustible waste.

In real life, you may also see:

• 可燃ゴミ
• 燃えるごみ
• 燃えるゴミ

They all refer to the same general category, though wording can vary by city or ward.

Because は is being used as the topic particle, and when は is a particle, it is pronounced わ, not は.

So:

• written: これは可燃ごみです。
• pronounced: これは かねんごみ です。

This is one of the first pronunciation exceptions learners meet in Japanese.

これ means this and refers to something near the speaker.

Japanese has a common set of demonstratives:

• これ = this
• それ = that (near the listener or previously mentioned)
• あれ = that over there

So in this sentence, これ is the thing being identified. The sentence structure is basically:

• As for this, it is burnable trash.

は marks the topic of the sentence.

In これは可燃ごみです。, the topic is これ (this). The speaker is saying something about this.

A very literal breakdown is:

• これ = this
• は = as for...
• 可燃ごみ = burnable trash
• です = polite sentence ending / is

So the overall pattern is:

• X は Y です
• As for X, it is Y.

This is one of the most basic sentence patterns in Japanese.

This is a very common beginner question.

In this sentence, は is used because the speaker is presenting これ as the topic: as for this...

If you used が, the nuance would shift more toward identifying the subject in a more specific or contrastive way. For example:

• これ は 可燃ごみです。 = As for this, it’s burnable trash.
• これ が 可燃ごみです。 = This is the burnable trash. / This is what counts as burnable trash.

So は is the natural choice for a simple labeling or explanatory sentence.

です is the polite copula. In beginner textbooks, it is often translated as is / am / are, though it does not behave exactly like the English verb to be in every situation.

Here, it makes the sentence polite and complete:

• これは可燃ごみです。

Without です, the sentence becomes less polite:

• これは可燃ごみ。

That sounds abrupt or like a label/sign rather than normal polite speech.

Because that is very common in Japanese.

The word ごみ can be written as:

• ごみ
• ゴミ
• 塵 or 芥 in rare/literary contexts

In everyday writing, ごみ or ゴミ is much more common than obscure kanji.

So 可燃ごみ mixes:

• kanji for the formal category word 可燃
• hiragana for the everyday word ごみ

That kind of mixed writing is completely normal in Japanese.

Yes. In normal Japanese, it would usually be written without spaces:

これは可燃ごみです。

The spaced version:

これ　は　可燃ごみ　です。

is mainly for learners, to make the parts easier to see.

Japanese does not normally put spaces between words the way English does.

Yes, especially in the context of trash sorting.

You will often see it:

• on garbage bags
• on trash collection calendars
• on signs near bins
• in city hall instructions

However, in casual speech, people might also say things like:

• 燃えるごみ
• 燃えるゴミ

The exact term depends on the municipality. Japanese garbage-sorting vocabulary can vary by area, so local wording matters.

It is polite and neutral.

Because it ends in です, it is suitable for:

• speaking politely
• classroom examples
• signs or explanations
• basic conversation

A more casual version would be:

これ、可燃ごみ。

or

これは可燃ごみだ。

But those are less polite. For learners, です is the safest form to use.

Yes: Japanese often puts the main label or predicate at the end.

English says:

• This is burnable trash.

Japanese says:

• This + topic marker + burnable trash + polite ending

So the important identifying information, 可燃ごみ, comes near the end.

This is a very common Japanese pattern:

• A は B です

Examples:

• これは本です。 = This is a book.
• それは水です。 = That is water.
• これは可燃ごみです。 = This is burnable trash.

Yes, it can.

Depending on context, これは可燃ごみです。 could be:

• someone explaining how to sort trash
• someone pointing at an item and classifying it
• written wording on an instruction sheet

On an actual bin or label, Japanese often drops parts and just writes:

• 可燃ごみ
• 可燃
• 燃えるごみ

So the full sentence is grammatically complete, but in real life, short labels are very common.

可燃 is a Sino-Japanese noun meaning combustibility or burnable/combustible in compound use.

In compounds, it works like a modifier:

• 可燃ごみ = combustible trash
• 可燃物 = combustible material

This is why it may feel a little more formal or administrative than a plain native-Japanese phrase like 燃えるごみ.

So learners should know:

• 可燃ごみ sounds like official sorting terminology
• 燃えるごみ may sound a bit more everyday and accessible

Both are useful.
