Clothing can be ligero (lightweight) but food can be, too. We use the adjective "light" for both meanings in English. Does anyone know if this parallel applies to other usages of "ligero" and light? E.g., can you do "light reading" in Spanish and indicate as much with "ligero"?

Light = lightweight. No doubt about it, since the coat's weight is what is being considered in the purchase. Please and thank you.
