What does the term "tirade" mean?

The term "tirade" refers to a long and often vehement speech or piece of writing that expresses strong criticism or anger. It conveys a sense of intensity and passion, typically criticizing something or someone over an extended period. This definition aligns perfectly with the choice identified as the correct answer, as it highlights both the length and the harshness characteristic of a tirade.

In contrast, the other options do not accurately capture the meaning of "tirade." A short, pleasant speech or a simple conversation lacks the critical and prolonged nature associated with a tirade. Additionally, a novel idea does not relate to speech or criticism and thus is not applicable in this context. Understanding "tirade" in terms of its emotional weight and context is essential for using the term effectively in language.
