Antonyms are words that have opposite meanings. When it comes to the phrase "conveyed impression," there are several possible antonyms. Rather than suggesting or communicating an idea, some words and phrases might indicate confusion, ambiguity, or a lack of clarity. For example, terms like "obscure," "disorienting," and "vague" all hint at a sense of uncertainty or confusion. Alternatively, a straightforward, unambiguous message might be described as "transparent," "clear," or "direct." These antonyms offer a range of options for conveying the opposite of the idea that a message or impression has been clearly conveyed or articulated.
