niebla
/ˈnjebla/ · B1 · noun · f
fog
🌫️ niebla comes from Latin nebula, mist, the same root as a space nebula
Latin nebula meant mist or cloud. Spanish changed the e to ie, as in tierra and piedra, and the u dropped out, which gave niebla. In English, nebula and nebulous come from the same word, and nebulous means hazy or unclear, like a foggy mind.
