dimension
📏 Cognate: dimensión = dimension, from Latin dimetiri, to measure out
Latin di- (apart) + metiri (to measure), the same root as metre. Spanish nouns ending in -sión are feminine, so it's la dimensión. It works like the English word, and also means scale or extent, as in la dimensión del problema.
