I have put together a comprehensive list of the 1000 most used words in Spanish with Spanish and English sentences.
Learning a language really takes time and effort. Don't be fooled. Ongoing dedication really will get you through.
You can use this list to build up your knowledge of Spanish words. It is a comprehensive list with examples of the words in English and Spanish to give you a good idea of how to use the word.
I recommend setting yourself achievable targets to make sure you stay on track with your learning. You could aim to learn 10 words (or less if you wish) a day. Five in the morning and five for the afternoon with the evening to check you remember them all. That may sound a lot to learn but consider all the times you have free when you could quickly learn a new verb. For example on the bus, waiting for the bus, on the toilet (when there are very few distractions!), during your lunch break, when you wake up in bed, when eating your breakfast, just before you shower (to practice in the shower), when you are waiting for someone; the list goes on and so do your opportunities to learn.
So don't be overwhelmed by learning a new language. Set yourself small daily goals and time will fly. Before you know it you will find yourself with an extensive vocabulary.
