The very best way to learn Spanish is total immersion. Since that's not possible for most people, the next best thing is to befriend a native speaker of Spanish and try to communicate in their language only.
Another way to learn is to get a hold of one of your favorite books that has been translated into Spanish and to read it out loud, preferably to someone else (like your Spanish-speaking friend).
Every method has its pros and cons. However, the more you communicate and the more senses you involve, the better the outcome will be.
Learn to ask the questions "
¿Qué es eso?" and "
¿Cómo se dice ____?" Repeat the answer you receive, ask for its spelling, write it down, look it up when you can. Make the word yours.
To make a word yours, create a short phrase or two that contains that word. That way you'll know what words work in conjunction with the new word. Remember, adjectives must agree in number and gender with the nouns they modify. In other words, learn '
la casa blanca' and '
las casas blancas' instead of just '
casa'; learn '
quiero comer' and '
quería comer', '
no lo sé' and '
no lo sabía'. The more phrases you know, the better. If you don't have access to verb conjugation charts, you can find one
here or
here (I entered the infinitive '
dar' to get these links, but you can substitute another infinitive at the end of the URL for tomisimo.org - you can also substitute another infinitive in the URL for conjugator.reverso.net OR you can enter a conjugated form of the verb to see what its infinitive is (and every other conjugation).)
