Cách sử dụng
The word 'oral' means something related to speaking or talking, rather than writing. For example, if you have an oral presentation, it means you have to talk about something in front of a group of people instead of writing it down. Another example is when you have an oral exam, you have to answer questions by speaking instead of writing your answers. So, if you hear the word 'oral' in the context of communication, it means something related to speaking or talking.
