kanozyo ha ketyappu wo kakenaide, kiiroi tamagoyaki wo sonomama tabemasu.

は marks 彼女 as the topic of the sentence.

So 彼女は means something like:

• As for her, ...
• She ...

It does not mean her is the subject in exactly the same way English works every time, but in this sentence it functions very naturally as she.

Because there are two different verbs, and each を marks the thing affected by its verb.

• ケチャップを かけないで = without putting ketchup on (it)
• 卵焼きを 食べます = eat the omelet

So:

• ケチャップを goes with かけないで
• 卵焼きを goes with 食べます

This is completely normal in Japanese.

かけないで comes from the verb かける, which here means to put / pour / drizzle / spread something onto something.

So ケチャップをかけないで means:

• without putting ketchup on it
• not using ketchup

In this sentence, ないで connects to the next action and means without doing X, do Y.

So the pattern is:

• Xないで、Yする = do Y without doing X

Here:

• ケチャップをかけないで、卵焼きを食べます
• She eats the omelet without putting ketchup on it

Japanese often leaves out information that is obvious from context.

In this sentence, the listener can easily understand that the ketchup would be put on the 卵焼き. So Japanese does not need to say it explicitly.

If you said everything fully, it might be something like:

• 卵焼きにケチャップをかけないで、卵焼きを食べます。

But this sounds repetitive, so the shorter version is more natural.

黄色い is an i-adjective meaning yellow.

It directly modifies 卵焼き:

• 黄色い卵焼き = yellow omelet

Grammatically, this is just like other i-adjectives:

• 赤いりんご = red apple
• 白い犬 = white dog
• 黄色い卵焼き = yellow omelet

Also, since 卵焼き is usually yellow anyway, this adjective may be adding a visual detail or a slight contrast for emphasis.

卵焼き (たまごやき) is a Japanese-style egg dish, usually a rolled omelet.

It is a single noun:

• 卵 = egg
• 焼き = grilled/fried/cooked

But together, 卵焼き means the dish as a whole.

So it is better to think of it as tamagoyaki / rolled omelet, not just any random cooked egg.

そのまま means:

• as it is
• without changing it
• plain
• just like that

In this sentence, it means she eats the omelet without adding anything, especially without ketchup.

So:

• そのまま食べます = eat it as is

This often appears with food:

• そのまま飲む = drink it as is
• そのまま食べる = eat it plain / without adding anything

A little, yes.

Both parts point in a similar direction:

• ケチャップをかけないで = without putting ketchup on it
• そのまま = as is / plain

Using both together adds clarity and emphasis. It feels like:

• She doesn’t put ketchup on it; she eats it just as it is.

So it is not wrong or unnatural. Japanese often uses this kind of mild repetition for emphasis.

The comma helps separate the two parts of the sentence:

• ケチャップをかけないで、
• 黄色い卵焼きをそのまま食べます。

It marks a pause between:

1. the without doing X part
2. the main action

Japanese commas are often used more flexibly than English commas, so this comma is helpful but not always absolutely required.

食べます is the polite form of the verb.

• 食べる = plain form
• 食べます = polite form

The meaning is basically the same, but 食べます sounds more neutral and polite.

Since the sentence also uses かけないで, which can be used in polite-style sentences, the overall sentence is in polite style because it ends with 食べます.

It could be either, depending on context.

食べます can mean:

• she eats (habitually / generally)
• she will eat (future)
• she is going to eat (depending on context)

So this sentence might mean:

• She eats yellow tamagoyaki plain, without ketchup
  or
• She will eat the yellow tamagoyaki plain, without ketchup

Japanese often leaves the exact time reference to context.

Yes, very often.

If the context already makes it clear who is being talked about, Japanese would often simply say:

• ケチャップをかけないで、黄色い卵焼きをそのまま食べます。

Japanese frequently omits subjects and topics when they are understood. Including 彼女は makes the subject/topic explicit.

Because here 黄色い is being used directly before the noun to describe it.

• 黄色い卵焼き = a yellow omelet

If you say:

• 卵焼きは黄色い

that means:

• The omelet is yellow

So the difference is:

• 黄色い卵焼き = adjective + noun
• 卵焼きは黄色い = complete sentence

In your sentence, the adjective needs to modify the noun because 卵焼き is the object of 食べます.
