The design is pretty, but it's a bit uncomfortable (but / and... so)

Both ~지만 and ~는데/은데 are used to connect two clauses with a contrasting meaning, similar to "but" in English. However, they have different nuances and uses.

Meaning & Usage

~지만 (but): This expresses a direct and clear contrast between two facts or situations. The first clause is acknowledged, but the second clause presents an opposing or unexpected reality. It's very straightforward.

Example: 한국어는 재미있지만 어려워요. (Korean is fun, but it's difficult.)

~는데/은데 (but / and... so...): This ending is more versatile.

1. Contrast: It can show a softer, less direct contrast than ~지만.

Example: 디자인은 예쁜데 좀 비싸네요. (The design is pretty, but it's a bit expensive.)

2. Background: It can provide background information or set the scene for the main point in the second clause. This is a very common usage in daily conversation.

Example: 비가 오는데 우산 있어요? (It's raining, so do you have an umbrella?)
