“Nosus decipio is nonsense, gibberish.”
I assume nos decipio would be correct?
No, because nos is first person plural and decipio is first person singular. Since nos can also be an accusative object as well as a nominative subject, it’s possible to read it as “decipio nos” (I deceive us) but that makes no sense in the context of the story.
Whoever wrote this is clueless.
“decipio” is first person singular. “nos” == “we” is
first person plural.
