IPA: //ʌnˈklaʊdi//
KK: /ʌnˈklaʊdi/
Clear and bright, without any clouds in the sky.
The weather was uncloudy, allowing us to see the stars clearly at night.
Uncloudy → It is formed from "un-" (meaning not) and "cloudy" (from Old English "cludig", meaning full of clouds). The word "uncloudy" means not full of clouds or clear.
Think of 'not' ('un-') being added to 'full of clouds' ('cloudy') — that's why uncloudy means clear.
