Feminine or masculine?!

Hi everyone! I really want to learn Spanish, first i thought that it was so easy but it's not that easy. I don't know which words are feminine or masculine. I'm going to give you an example for what i mean. Example I live in Holland = Yo vivo en Holanda (masculine) Yo viva en Holanda (feminine) Not all words are feminine or masculine, my question is how do you know if a word have a feminine and a masculine form???? Please help me, thanking you in advance!

In Spanish, nouns can be masculine or feminine, as can the adjectives that accompany them. Verbs in Spanish do not have gender. *Yo vivo* uses the first-person singular _indicative_ form of the verb vivir, while *yo viva* uses the first-person singular _subjunctive_ form of vivir. Both mean "I live," but the subjunctive is used in certain circumstances that you'll learn as you become more proficient in Spanish. I strongly recommend that you take a look at the grammar materials that accompany the Rocket Spanish course.
