"Envintion" is not a recognized word in the English language. It's likely a misspelling of one of the following words:

* Invention: This refers to the creation of something new, a novel idea or device.

* Convention: This refers to a large gathering of people for a particular purpose, like a conference or meeting.

* Environ: This is a rare archaic word meaning "surroundings" or "environment."
