nivelar
/nibeˈlaɾ/ · B1 · verb
to level out, to make even
⚖️ nivel = level, so nivelar = to level something out
Spanish nivel and English level both come from Latin libella, a small balance scale, from libra (scales). So nivelar means to make even, to balance, or to measure height with a level, which is how surveyors use it.
