wǒ yǒngyuǎn búhuì wàng.

In Chinese, adverbs like 永远 usually come before the verb phrase they modify.

So:

• 我永远不会忘。 = I will never forget.

Here, 永远 modifies the whole idea of 不会忘.

If you said 我不会永远忘, it would sound strange and would suggest something more like I won’t forget forever, which is not the intended meaning.

A simple way to remember it:

• subject + adverb + auxiliary/modal + verb

So this sentence follows a very common pattern:

• 我 = subject
• 永远 = adverb
• 不会 = negative/modal element
• 忘 = main verb

不会 literally means will not, won’t, or sometimes cannot depending on context.

In this sentence, 不会忘 means will not forget.

So:

• 我永远不会忘。 = I will never forget.

If you said 我永远不忘, it is grammatically possible, but it sounds more literary, formal, or slogan-like. In everyday speech, 不会忘 sounds more natural for a future-oriented promise or statement.

Compare:

• 我永远不会忘。 = I will never forget.
• 我永远不忘。 = I never forget / I shall never forget.
  This is shorter and more forceful, but less conversational.

Here it means will not, not cannot.

That is important because 不会 can have different meanings in different sentences:

• 我不会说中文。 = I cannot speak Chinese / I don’t know how to speak Chinese.
• 我不会忘。 = I will not forget.

In 我永远不会忘, the meaning is not about lack of ability. It is about determination or certainty.

So the sentence means:

• I will never forget not
• I am unable to forget

This is because of a common Mandarin tone change rule.

Normally:

• 不 is fourth tone: bù

But when 不 comes before another fourth-tone syllable, it changes to second tone:

• 会 is fourth tone: huì
• So 不 + 会 becomes bú huì

That is why the pinyin is written:

• 不会 = búhuì

This is just a pronunciation change; the character 不 does not change.

Other examples:

• 不是 = bú shì
• 不要 = bú yào
• 不对 = bú duì

永远 means forever or for all time.

In a negative sentence, it often gives the meaning never:

• 永远不会忘 = will never forget

So even though 永远 literally has the sense of forever, the full phrase naturally becomes never in English when combined with 不会.

Examples:

• 我永远爱你。 = I will love you forever.
• 我永远不会骗你。 = I will never lie to you.

So in this sentence, 永远 adds strong emotion and permanence.

Yes, 忘 can be used by itself.

Both 忘 and 忘记 can mean to forget.

For example:

• 我不会忘。
• 我不会忘记。

Both are correct.

A general difference:

• 忘 is shorter and often a little more direct or natural in speech.
• 忘记 is the fuller form and can sound slightly more complete or formal.

In this sentence, 我永远不会忘 is very natural and emotionally strong.

You could also say:

• 我永远不会忘记。

That means the same thing, with only a small difference in style.

Chinese often leaves out an object when it is already understood from context.

So 我永远不会忘。 is a complete sentence even without saying what is being forgotten.

Depending on context, it could mean:

• I will never forget you
• I will never forget this
• I will never forget what happened
• I will never forget that moment

If you want to make it explicit, you can add the object:

• 我永远不会忘你。 = I will never forget you.
• 我永远不会忘这件事。 = I will never forget this matter.
• 我永远不会忘记那一天。 = I will never forget that day.

So the object is omitted because it is understood.

Yes, it usually sounds quite strong and emotional.

Because of 永远, the sentence does not sound neutral. It sounds like:

• a promise
• a heartfelt statement
• a dramatic memory
• an emotional response

For example, someone might say it after:

• receiving great kindness
• experiencing a major life event
• saying goodbye
• remembering something painful or meaningful

So 我永远不会忘。 is stronger than just:

• 我不会忘。 = I won’t forget.

Adding 永远 gives it a deeper, more lasting feeling.

Yes. That is completely natural.

These two are both correct:

• 我永远不会忘。
• 我永远不会忘记。

The difference is mostly stylistic:

• 忘 = shorter, punchier
• 忘记 = fuller, slightly more explicit

In many situations, native speakers would accept both with almost no change in meaning.

If you are unsure, both are safe choices. The version with 忘 may sound a little more concise and emotional.
