"It is cold outside."

Translation: 밖은 추워요.

[RodSalomon1]

Baby, it's cold outside

[IceCreamCrackers]

아기, 밖은 추워요.

[PhuHung18]

is is ok if i say "밖에 주워요"?

[John450762]

Not fluent, but I imagine 밖은 more explicitly states that "The outside is cold" whereas 밖에 would mean "Something outside is cold."

[SuperSizedSmiley]

What about 밖에서?

[notstarboard]

I don't think this makes sense because there isn't an action happening outside. It's just being described as cold.

How about 밖에는 추워요?

[mhin1]

That sounds strange to me since 밖 is already a noun for "the outside space".

"밖은 추워요?" is better.

밖에 추워 is what I heard countless times during my years in Korea. Duolingo accepts this version as correct.
