You can't memorize words by rote. The human brain has a forgetting cycle. In order to fight against forgetting, it is best to remember words in context. Context here refers to sentences, paragraphs, essays, etc. Memorizing meaningful words, using the ability of association and understanding, it is easier to remember the meaning and usage of words. The words recorded in this way can not only remember its meaning, but also remember its usage. Even if you forget the word next time, think about the context in which it is located, and you can recall it. This is my experience of listening to the teacher in the open class of Beijing Nuojia English Training School directly under Beijing Foreign Studies University. I tried it myself and it worked well. I hope it helps you!
