It's possible you were trying to spell one of the following:
* Hypnotic: This word refers to something that induces hypnosis, or a trance-like state.
* Synoptic: This word means "providing a general view or summary," often referring to a concise and comprehensive account of something.
If you could provide more context or the sentence where you saw this word, I might be able to help you figure out what it was supposed to mean.
