The Vietnamese word "độc thoại" translates to "monologue" in English. It refers to a speech or a piece of writing in which a single character speaks to themselves or to an audience without interruption from others. This can be seen in plays, movies, or literature where one person expresses their thoughts or feelings.
While "độc thoại" primarily refers to a monologue, it can also imply a situation where one person is dominating the conversation in a social context, even if it is not part of a formal speech or writing.
