The word "am told of" can have several antonyms, depending on the context in which it is used. In a positive sense, the antonyms could be "am aware of," "am informed of," or "am knowledgeable of." These antonyms would suggest that the speaker is reasonably familiar with a particular issue, event, or situation. In a negative sense, the antonyms might be "am ignorant of," "am uninformed of," or "am unaware of." These antonyms would indicate that the speaker has little or no knowledge of a particular subject or circumstance. Whatever the antonym, the phrase "am told of" implies that the speaker has received information from an external source, rather than discovering it for themselves.
