You can use the dictionary at any time while studying with a course. Simply highlight the word or part you want to translate and click the dictionary icon that appears on the left side. The dictionary will automatically detect the language from which it is to translate. You can also search for any word or phrase that comes to mind by clicking the three dots in the upper right corner of the screen and selecting "Dictionary."
