The most common antonyms for the term "most plain spoken" would be words like embellished, ornate, and verbose. These words describe language that is layered with elaborate details, flowery language, and fancy vocabulary. The contrast between plain spoken and ornate language highlights the distinction between simplicity and complexity in speech. While plain spoken language is simple and direct, ornate language often hides the intended meaning behind a barrage of unnecessary words. When communicating with others, it is essential to know when to use plain spoken language to convey a message effectively and efficiently. However, ornate language can be useful in certain situations, such as when the goal is to persuade or impress others with one's knowledge or rhetorical skills.
