I strongly advise yo take care of oral skills, and grammar will come by itself. Make a good network of partners and start speaking as soon as possible. As Page says, in spanish we have only five vowels, and only five vowel sounds. Thus, it is easy start to speak. And as Rodrigo says, Duolingo is a good method for self introduce you in the language, and adquire basic knowledge of the language. Un saludo

Hello Aina, First of all to learn Spanish you gotta understand that this language is highly phonetic. If you properly learn no pronounce the vowels you are going to be 20% of the road there because the vowel sound does not change. Ever. Second we use subject first and then the adjective. Blue Pans will be Pantalones –Pans– Azules –Blue–. Like always. Start with that knowledge in your mind and you will be able to get it faster.

Go to Duolingo and fi3m.com

I highly recommend start by learning the Spanish Alphabet... El Alfabeto. Youtube has a lot of great videos for kids to learn the Spanish alphabet.

Creo que debes aprender las palabras que más amas de tu lengua nativa, las que más utilizas, de esa manera entrarás al aprendizaje del español a través del afecto.
