What is the meaning of "garrulous"?

The term "garrulous" refers to someone who is excessively talkative, particularly about trivial or unimportant matters. It suggests a tendency to engage in lengthy discussions or conversations that lack depth or significance. This word often has a negative connotation, implying that the individual may be overwhelming or tiresome to others due to their chatter.

In contrast, the other choices describe characteristics that are not aligned with the definition of "garrulous."
