What does undeceived mean?
Undeceived describes someone who is no longer under a false or misleading impression. It can suggest simple recognition that a claim, appearance, or expectation was not trustworthy, as in “unfounded by the evidence,” but it often carries a more emotional nuance: the person has been disappointed or disenchanted by what was discovered. The word may describe the correction of a belief, the loss of confidence in someone or something, or the result of removing deception from a situation. In its participial use, it commonly follows a verb such as remain, leave, or be. Although undeceived is precise and expressive, everyday speakers often prefer disenchanted, disillusioned, or disappointed. It remains useful because it captures both the intellectual recognition of error and the emotional consequence that may follow.
No longer deceived or misled; disenchanted or disappointed after a false belief has been corrected.
"The skeptical customer remained undeceived by the exaggerated claims."
Common with by and sometimes with about; it can be formal or literary.
