ragu, buranketto, kussyonkabaa, karaasanpuru, kansetusyoumei wo kuraberu.

Because the entire list is treated as one direct object of 比べる.

In Japanese, when you list several nouns and they all receive the same action, you often list them first and then put a single を after the final item:

• ラグ、ブランケット、クッションカバー、カラーサンプル、間接照明 を 比べる。

This means compare rugs, blankets, cushion covers, color samples, and indirect lighting.

You do not need to attach を to each noun.

、 is the Japanese comma. It separates the items in the list, just like commas in English.

So this sentence is basically structured as:

• rug,
• blanket,
• cushion cover,
• color sample,
• indirect lighting,
• object marker
• compare

At the end, 。 is the Japanese period.

They are mostly loanwords or product-style vocabulary, so katakana is natural.

For example:

• ラグ = rug
• ブランケット = blanket
• クッションカバー = cushion cover
• カラーサンプル = color sample

Katakana is commonly used for:

• foreign loanwords
• brand/product terminology
• modern commercial vocabulary

This sentence sounds like something from interior design, shopping, or product selection.

Because 間接照明 is a native Sino-Japanese term, not a borrowed English-style word.

It is read かんせつしょうめい and means indirect lighting.

Breakdown:

• 間接 = indirect
• 照明 = lighting / illumination

Japanese often mixes katakana loanwords and kanji-based terms in the same sentence, especially in fields like design, furniture, and home décor.

Because Japanese is basically an SOV language: subject - object - verb.

So instead of saying:

• compare rugs and blankets

Japanese naturally says:

• rugs and blankets を compare

That is why 比べる comes at the end.

比べる is the dictionary form of the verb, meaning to compare.

Depending on context, dictionary form can be used in several ways:

• as a plain statement in notes/headings
• as a neutral citation form
• as a casual statement
• as a label or task description

In a sentence like this, it may sound like:

• Compare rugs, blankets, cushion covers, color samples, and indirect lighting.
• or a heading like Comparing rugs, blankets, cushion covers, color samples, and indirect lighting

So the exact English phrasing depends on context.

Yes, possibly—but Japanese often leaves the subject unstated when it is obvious from context.

This sentence could mean things like:

• I compare ...
• We compare ...
• Compare ...
• To compare ...

Japanese frequently omits subjects if they are not necessary. In a product catalog, worksheet, or presentation slide, this kind of sentence can stand alone very naturally.

Both can mean to compare, but 比べる is the more basic, everyday verb.

• 比べる = common, natural, conversational
• 比較する = more formal, technical, academic, or business-like

In a simple product-selection sentence, 比べる sounds very natural.
If you used 比較する, it would feel a bit more formal:

• ラグ、ブランケット、クッションカバー、カラーサンプル、間接照明を比較する。

That is also correct, just slightly more formal in tone.

Yes, but the structure changes.

A very common pattern is:

• AとBを比べる = compare A and B

Here, と links the things being compared.

But when you are simply listing multiple items, as in your sentence, Japanese can also just list nouns with commas and then use one を at the end.

So both styles are possible depending on how the sentence is built.

Examples:

• AとBを比べる = compare A and B
• A、B、Cを比べる = compare A, B, and C

It is a loanword-style expression that Japanese speakers would understand naturally, especially in design, printing, fashion, or interior contexts.

Even if the source is English, katakana words in Japanese often develop their own normal usage. So カラーサンプル is not just random English spelling—it functions as a real Japanese vocabulary item.

In context, it likely means something like:

• color swatch
• color sample
• sample of a color/material option

It can be either, but it very often sounds like a heading, instruction, or note rather than a complete conversational sentence.

Because it uses:

• a plain dictionary-form verb
• no stated subject
• a simple object list

it feels very natural in contexts like:

• a presentation slide
• a design brief
• a to-do list
• a catalog section
• a lesson heading

So it may read like:

• Compare rugs, blankets, cushion covers, color samples, and indirect lighting rather than a fully conversational sentence like
• I will compare rugs, blankets, cushion covers, color samples, and indirect lighting.

In conversation, a speaker might add more context, such as:

• ラグとかブランケットとかクッションカバーとか、カラーサンプルや間接照明を比べる。
• ラグやブランケット、クッションカバー、カラーサンプル、間接照明を比べる。

Using や or とか can make the list sound more conversational and less like a formal written list.

Your original version is perfectly correct, but it has a neat, written, list-like feel.
