The antonym for the word "am quiet" can be loud, noisy, or boisterous. These words describe a person who speaks or behaves in a manner that is not peaceful or calm. Instead, they tend to be more outgoing, assertive, or even aggressive. Being loud or noisy can sometimes be seen as a negative trait, as it may be seen as rude or annoying to others. However, it can also be an expression of excitement or enthusiasm. In contrast, being quiet may signify a sense of peace, reflection, or introspection, but it can also communicate a lack of confidence or assertiveness.
