The YouTube playlist includes idioms professionals can use directly on the job in situations when they need to be fluent and confident. Research in the field of Linguistics has shown that the use of idioms decreases cognitive load - allowing you to focus on things that matter. Using idioms also increases fluency and demonstrates competence. In this list, it is demonstrated how the idiom is used in real life, how to look it up in different dictionaries (i.e. dictionary definitions are included in these videos), and what to do next to be able to acquire them. Please note that you would need to use them at least 7 times afterwards to make that happen.
