The word matter means: "materia, asunto, tema" in Spanish. My question is: Can we use matters in plural with the meaning of "materias, asuntos, temas", or we use this word in singular always?

My other question is about the title of the first lesson of my English book: Fashion matters. Does this mean: "La moda importa", or "asuntos de moda"?

Answer

Hi Christina I'm not spanish but here what I have found as explanations.
When matter is a noun, and when there are many kind of matters, in reference to various types of matters then the plural form is matters.
Examples:
One matter has been dealt with.
Two matters will be fixed going forward.

And Fashion matters means "la moda importa"; I think matter is a verb in this case. And the verb takes an -s with the third-person singular form.
