kiken wo sakemasita.

It is read:

きけん を さけました
Romanized: kiken o sakemashita

A natural pronunciation of を in modern Japanese is basically o, even though the kana is written を.

The dictionary form is 避ける (さける), which means to avoid.

So:

• 避ける = dictionary/plain form
• 避けました = polite past form

In this sentence, 避けました means avoided.

を marks the direct object of the verb.

Here, the verb is 避けました (avoided), so the thing being avoided is marked with を:

• 危険 = danger
• 危険を = danger (as the thing being avoided)

So the structure is basically:

[object] を [verb]
危険を 避けました
= (Someone) avoided danger

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

So 危険を避けました could mean:

• I avoided danger
• He avoided danger
• She avoided danger
• They avoided danger

The exact subject depends on the situation or earlier conversation.

This is very normal in Japanese and is one of the first things English speakers have to get used to.

危険 (きけん) means danger or dangerousness, depending on how it is used.

In this sentence, it is a noun meaning danger.

So:

• 危険を避けました = avoided danger

Also note that 危険 can be used like a na-adjective before a noun:

• 危険な場所 = a dangerous place

But here it is just a noun, not an adjective.

ました makes the verb:

• polite
• past tense

So 避けました is the polite past form of 避ける.

Compare:

• 避ける = avoid / to avoid
• 避けた = avoided (plain past)
• 避けます = avoid / will avoid (polite non-past)
• 避けました = avoided (polite past)

So this sentence is in a polite style.

In this verb, yes: 避ける is read さける.

Be careful, because Japanese has other words that may look or sound similar. For example:

• 酒 = さけ = alcohol / sake

That is a completely different word.

So in this sentence:

• 避けました = さけました = avoided

Yes, it is grammatically natural, though by itself it feels a little context-dependent.

Japanese often allows short sentences like this, especially when the subject is already understood.

For example, in a story or conversation:

• 危なかったですが、危険を避けました。
  It was close, but I avoided danger.

On its own, 危険を避けました is a perfectly fine sentence, just somewhat concise.

This is a very common question.

• 避ける = to avoid
• 逃げる = to run away / escape

So:

• 危険を避ける = avoid danger
• 危険から逃げる = run away from danger

避ける focuses on not coming into contact with something bad.
逃げる focuses on fleeing from it.

They can sometimes be similar in meaning, but they are not the same verb.

No. It can refer to physical danger or more abstract risk, depending on context.

For example, it could mean avoiding:

• an accident
• a dangerous area
• a risky situation
• trouble or harm

Japanese often leaves that wider context unstated unless needed.

Yes. 危険を避けた is the plain past version.

Compare:

• 危険を避けました = polite
• 危険を避けた = plain / casual

Both mean essentially avoided danger, but the tone is different.

Use 避けました in polite conversation, formal writing, or when speaking respectfully.
Use 避けた in casual speech, diary style, or informal narration.

This is standard Japanese writing.

• Content words like nouns and verbs are often written with kanji
• Particles like を are written in hiragana

So the sentence mixes kanji and kana in the normal way:

• 危険 = kanji
• を = hiragana particle
• 避けました = kanji + hiragana ending

This mixed writing style is how most Japanese sentences are written.

Yes. The pattern is very flexible:

[thing to avoid] を 避けました

For example:

• 事故を避けました = avoided an accident
• 渋滞を避けました = avoided traffic
• 問題を避けました = avoided a problem
• 人混みを避けました = avoided the crowd

So 危険を避けました is one example of a very common grammar pattern.
