Xilat mi’hiju (the sky is cloudy) and its negation are about the only times when this word is used as a state verb. Apart from that, the adjective refers to clouds and the noun, well, is explained in the topic pretty well already. The word is used in a previous posting already. Namely in the song “A la barikadoj”. Which made me remember that I never actually got around to record it. Which I did now. Listen at your own risk.
EDIT: Sorry, I didn’t realize that audacity *bleep*ed up so royally!
