How to Say "stay away" in Spanish
The Spanish word for “stay away” is “aléjense” — A2 level. This is a very common word in everyday Spanish.

Examples
¡Aléjense de las vías del tren!
Get away from the train tracks!
Por favor, aléjense para que los paramédicos puedan trabajar.
Please, move back so the paramedics can work.
Aléjense de los problemas si quieren tener una vida tranquila.
Stay away from trouble if you want to have a peaceful life.
Understanding the 'se' at the end
This word is a 'reflexive command.' The 'se' at the end tells the group of people to move themselves. In Spanish, when you give a positive command, the 'self' word (pronoun) attaches directly to the end of the verb.
The Accent Mark Rule
Because we added the 'se' sound to the end, we have to add a written accent on the 'e' (aléjense) to make sure the emphasis stays on the right syllable when we say it.
Putting 'se' in the wrong spot
Correction: Always say 'aléjense' for positive commands. Only put 'se' before the verb if you are saying 'don't' (No se alejen).
