The Spanish phrase "bellas latinas" translates into English as "beautiful Latin girls" or "females." Even though the phrase in Spanish doesn't include a word for "girl", the gender is inferred in the suffix "as".
Spanish, as a Romance language, is gender specific. This means that everything, even inanimate objects, is referred to as being male or female. When an object is "male" the word ends with the letter "o," and when the subject is female, the last letter is "a." If there is more than one subject, the plural forms with an "s" at the end of the word regardless of gender.
