Words on their own do not have meaning, only meaning potential. In order to mean something, a word must enter into a relationship with other words in a sentence (expressed or implied), with a co-text, and with a context.
I therefore do not recommend studying words in isolation. In fact, I urge people not to do that.
And yet I am about to offer words without context. Huh? What up with that? Well, I offer these words by way of review, with an exclusive focus on their pronunciation. The Academic Word List (AWL) was put together by Averil Coxhead at Victoria University in Wellington, New Zealand. You can read about it here. In my 13 years as a university lecturer, I came across many students, teachers, and professors who mispronounced many of the words on this list, although they were able to understand them when they came across them in their readings. And so I had the idea of offering the pronunciation of these words in 5-word units. If you find that you don't know a substantial number of these words, you can study them with the help of a variety of AWL study books. One such book was written by Helen Huntley. It's called "Essential Academic Vocabulary: Mastering the complete Academic Word List." While that book is useful for learning the meaning of the words in context, it does not help you with the pronunciation of these words at all. But pronunciation is the gateway to and the essence of a language, and so I urge you to include the study and practice of pronunciation in your studies.
So, enjoy saying and tasting all those words, even if you think you know them. And if you find that you need help with pronunciation matters or any other matter related to learning and using English, contact me at email@example.com.
