Did you find the answer?!?!?!?!?!

 

If you were born deaf. What language do you think in?

 

well doctor goodle says:
The difference in terms is a matter of how much cloud cover there is. Interestingly, partly sunny and partly cloudy mean the exact same thing—but partly cloudy is the correct term for nighttime conditions because you can't see the sun. “Fair” skies is another cloud cover term that's sometimes used.
