Does the Spanish word "Varones" only refer to men or can it include women in its definition as well? From my understanding it only means males/men. But I want to make sure about this. Thanks.
A varón is, indeed, a male human. Currently, this word is only used to emphasize the sex of the person we are talking about, so it would translate to male in English on most situations.
The word hombre, on the contrary, can be used for a male human or in a generic sense, much as the word man is used in English, for the human species or unspecified people:
El hombre habita la Tierra desde hace un millón de años (generic; it includes men and women).
El hombre es el más longevo de los mamíferos (generic; it refers to the species, regardless of sex).
Deseo la paz entre todos los hombres (generic, once again).
