Q: Is it right to say "in the open sky' instead of "outdoors"? Can outdoors and in the open sky be synonyms?
I find these two terms really confusing.

A: You can say outdoors or in the open air.

A: I don't think it is wrong but I would say "under the open sky."

A: Aside from under the open sky, you could also pluralize the phrase and say under the open skies.

Now get to work, unless you enjoy sleeping under the open skies.

Alternately, and depending on context, consider the French phrase à la belle étoile, which means:

à la belle étoile [= under the beautiful star] in the open air at night.


A: Yes, you can and should use open sky — or you could choose one of these terms to express the idea:
