What type of speech does "tirade" imply?

The term "tirade" specifically refers to a long, angry speech or piece of writing that expresses strong criticism or complaints. This indicates that it is not just a simple or brief statement, but instead involves an extended elaboration on grievances or discontent. In essence, when someone delivers a tirade, they are often venting frustration or dissatisfaction at considerable length, providing ample opportunity to explore their negative feelings. This is why the indication of a lengthy complaint aligns perfectly with the meaning of the word, distinguishing it from more neutral or constructive forms of communication such as supportive dialogue, brief statements, or informative discussions.
