Though usually, it is something that improves over a long period of time, there is one shortcut you can try. But it is quite tedious. What you need are recorded conversations. You can find these on youtube or podcasts. The best ones would be where there are many short questions and answers; as opposed to long monologues. You should listen to the conversation and then replay it and pause after each question. And here you should answer and try to reproduce the message of the original answer in your own words. And maybe write down your answer. Then play the actual answer and compare the words and sentence structure you used to those used by the speaker. You will to notice certain words and patterns. And the more conversations you do this with, the more you will internalise the word usage. The above method is derived from how Benjamin Franklin improved his writing by reading something and then writing it in his own words to compare the words and structure he used to that of the author. The working behind the method is that to learn something, you need practice. And you need feedback on your practice.
