Phrasal verb: Go out

Hi,

Go out (Oxford dictionary): To leave your house to go to a social event.

So, if I go out of my house, not to go to a social event, can I also say:

I go out to see in the sky in order to know if it rains. (a)

Thanks
K

P.S: Please correct (a) if it is ungrammatical.

.
Yes, you can use “go out” that way (when go out of your house is understood, for example), but your sentence is bad grammatically and also somewhat nonsensical.

I went out and looked at the sky in order to estimate the likelihood of rain.

(If it had already been raining, you wouldn’t have needed to specifically look at the sky, in my opinion.)
.

Interesting,

Many thanks.
