This is kind of a hard question to answer. There are so many ways to learn English. If you don't have anyone close by that could answer or explain what a word is, you could google search it, and if it has a picture associated to it, tell yourself a sentence story using the word and keep that image in your head. The other thing is to constantly practice. If you study here or there and there are large gaps or you don't get enough practice, you'll quickly lose the information you had gained. There are so many sources that you can use, such as Youtube, books, movies, TV shows. Other English speakers can help fill any gaps or explain words you don't understand. You just have to put in the time.
