"이 식당이 안 어두워요."

Translation: This restaurant is not dark.

[DidYouGetAWopper]

Yeah, you're just blind.

[AspryWrites]

good to know.

[Druckles]

What's the root here? Dark is 어두운, so would to be dark be 어두웁니다 in 합소제?

[wintertriangles]

어둡다 is the infinitive "to be dark", but yeah your formal version is right

[AndyBuGo]

Why does the conjugation of the adjective ends in 워요? What level of Korean?

[mhin1]

어둡다 is a ㅂ-irregular verb. For polite (and casual) Korean, you need to alter the stem before conjugating:

어둡다 → 어두우 → 어두우+어요 = 어두워요

[ifnt0618]

어둡습니다 is right.

What is the difference between "안" and "않아요"? In the sense.... 안 He stands in front of an adjective and "않아요" ? I don't know.... Tell me if I'm wrong.... I don't really understand... They are both "no" but where you go to put "안" and "않아요".

You've noticed a quirk of verb negation in Korean. There are many (6?) ways to negate verbs in Korean, depending on the sentence mood and how strongly you are negating the verb.

• 이 식당이 안 어두워요 = "This restaurant is not dark."
• 이 식당이 어둡지 않아요 = "This restaurant is not dark."

The short negation just places the adverb 안 before the verb. The long negation uses the verb auxiliary (for the declarative mood) ~지 않다 and conjugates the new verb.

Should 'gloomy' be accepted? I learned dark / gloomy as equal translations but was wrong.

[Mini-Shooky]

안 means not do in relation with the verb, right?

[mhin1]

네, 맞아요. That is right.

[taesvlive]

could you also say "이 식당이 어둡지 않아요" ?
