Here's a possible breakdown:
* "In" is a preposition in English, Spanish, and many other languages.
* "Esta" is the Spanish word for "this".
* "Vien" is not a recognized word in any major language. It might be a misspelling of "viene" (Spanish for "comes") or "vient" (French for "comes").
To understand what the intended meaning is, you'll need more context.
Please provide more information, such as:
* Where did you see this phrase?
* What was the context of the conversation or text?
* What language was it intended to be in?
