서늘하다: This word often describes a chilly or cool feeling, usually in the atmosphere or weather. It can convey a coolness or a slight chill in the air. Example: 가을 바람이 서늘하다. 선선하다 : Similar to 서늘하다, 선선하다 is also used to describe cool and refreshing weather or atmosphere. However, it is generally milder than 서늘하다 and implies a pleasant and comfortable coolness. Example: 오늘은 선선한 바람이 불어서 산책하기 정말 좋은 날이다. 썰렁하다: 썰렁하다 is quite different from the previous two. It describes something dull, boring, or lacking in excitement. It is often used to express a lack of interest or enthusiasm. Example: 그 남자의 유머는 너무 썰렁했다. In summary, 서늘하다 and 선선하다 are related to the weather and atmosphere, describing coolness with 서늘하다 being slightly colder in tone. 썰렁하다, on the other hand, is used to express boredom or lack of interest.

Both 엄청 and 엄청나다 are used to emphasize large scale or degree, but there may be some differences. 엄청 is usually used as an adverb (부사) and refers to a state or degree of being very large or strong. 예: 집이 엄청 크다. / 옷이 엄청 예뻐서 사고 싶었다. 엄청나다 is used as a verb (동사), mainly to indicate that something has an extremely large or surprisingly strong characteristic. 엄청나다 is usually used to express surprise or admiration. 예: 그 집 크기가 엄청나다. / 피아노 연주 실력이 정말 엄청나다. 엄청 is a common expression emphasizing size or degree, and 엄청나다 is mainly used to express surprise or surprise.

Hello Zoha Shiran, According to the "Standard Korean Dictionary (표준 국어 대사전)," "Experience (경험)" means "knowledge or skill that you have actually tried or experienced," and "Experience(체험)" means "experience or experience that you have in person." According to this interpretation, it is difficult to say that "experience(경험)" and "experience(체험)" are words that clearly distinguish the context in which they are used. However, just as "experience handwriting(체험 수기)" is more natural than "experience handwriting(경험 수기)" and "a vivid experience (산 경험)" is more natural than "a vivid experience(산 체험)," there may be differences in the degree of "naturalness(자연스러움)" depending on the context. I hope this answer is helpful.

Hi, Chiara pp I think it's better to fix it like this. 1. 원래는 친구랑 영어를 같이 배우고 그랬는데, 저도 모르게 우리가 되게 친해졌어요. or 원래는 친구랑 영어를 같이 배우고 그랬는데, 갑자기 우리가 되게 친해졌어요. " 저도 모르게" and "갑자기" are similar expressions, so you don't have to use both together. It would be natural to choose one or the other in a sentence. 2. 중학교때는 수업이 일찍 끝나서 밥을 집에서 먹고 오후에 친구랑 놀고 그랬어요. We don't say "수업들" in the plural.

천만에요.
