What can be an effect of using overly complex vocabulary?

Using overly complex vocabulary can indeed have the effect of alienating the audience. When communication is filled with jargon or intricate language that is not easily understood by the listener, it creates a barrier to effective understanding. This can lead to confusion or disengagement, as individuals may feel excluded or intimidated by the complexity of the language being used. Clear and straightforward communication is essential in ensuring that the message is accessible to everyone in the audience, which fosters better interaction and understanding.

In contrast, the other options suggest positive outcomes that may not occur with complex vocabulary. For instance, while some might believe that using sophisticated language enhances understanding or demonstrates mastery, it can have the opposite effect if the audience struggles to grasp the concepts being discussed. Furthermore, complex vocabulary typically complicates a message rather than simplifying it. Effective communication should prioritize clarity and connection with the audience, rather than showcasing a high level of vocabulary that may not be beneficial in every context.
