I think you would have done it better in Korean 🇰🇷

Sentence info.

The Korean sentence can be constructed as:
 내 생각에는 네가 그걸 더 잘했을 거야.
Romanized: nae saenggage-neun ne-ga geugeol deo jalhaesseul geoya.

Breaking it down:
1. 내 생각에는 (nae saenggage-neun) – “in my opinion” or “I think”. This phrase sets the speaker’s viewpoint.
2. 네가 (ne-ga) – “you” as the subject. The subject marker 가 indicates that “you” is performing the action.
3. 그걸 (geugeol) – “it” as the object, with 걸 being a contracted form of 그것을.
4. 더 (deo) – “more,” which intensifies the following adjective, implying “better.”
5. 잘했을 거야 (jalhaesseul geoya) – This is derived from the verb “잘하다” (to do well) modified to express a past hypothetical result with the future presumptive form 거야. The structure “-았/었을 거야” is used to indicate that something “would have” happened or “should have” happened.

Tips to remember:
• Notice that Korean often places the speaker’s perspective first (내 생각에는) to clearly state “I think.”
• The subject (“you”) and object (“it”) use particles to mark their roles: 가 for the subject and 을 (contracted in 걸) for the object.
• The phrase 더 잘했을 거야 uses a combination of an adverb (더), the verb in past form with a modifier ending (잘했을), plus 거야 to indicate a supposition about a past event.
• Remember the pattern: [Opinion phrase] + [Subject + Object] + [Adverb + Verb (past hypothetical form) + 거야] for similar expressions.

Alternate expressions:
• 내 생각에는 네가 그걸 좀 더 잘했었으면 좋았을 텐데.
 Romanized: nae saenggage-neun ne-ga geugeol jom deo jalhaesseosseumyeon joasseul tende.
This variant adds a wishful nuance implying regret that things didn’t happen as well.

• 난 네가 그걸 더 잘했을 거라고 생각해.
 Romanized: nan ne-ga geugeol deo jalhaesseul georago saenggage.
Here the construction is slightly rearranged, directly inserting ‘생각해’ (“I think”) after the estimated outcome.

Both alternatives convey the idea that you believe the action could have been performed better.
