limpieza
/limˈpjeθa/ · B1 · noun · f
cleanliness
🧽🧼 limpio (clean) + -eza (-ness) = clean-ness; cousin of English limpid
Limpio comes from Latin limpidus, clear, which also gave English limpid, as in limpid water. The suffix -eza works like English -ness, the same as in tristeza (sadness). So limpieza is clean-ness, and also the act of cleaning.
