The phrase "conveys the impression" refers to the act of communicating a certain perception or understanding about something. Antonyms for this phrase might include words like obscure, distort, mislead, confuse, or obfuscate. Rather than conveying a clear impression or message, these words suggest a deliberate or unintentional attempt to obscure or misrepresent the true picture. When we say that something "obscures" the impression or message, we mean that it makes it more difficult to decipher or understand. Similarly, when we describe something as "misleading," we suggest that it creates a false or inaccurate understanding of what we are trying to communicate.
