Decir en inglés  «esto esta relacionado con…» es uno de los errores comunes en los que más se cae.

What you should say: To be related to

Once again, the direct translation will lead to a common mistake. ‘To be related to’ can mean that one ‘is connected to, comes form, or is very similar to another thing’. We also use ‘related to’ to speak about being family with another person: I think I’m related to you.

Is this related to the last memo?

Are you really related to Abraham Lincoln?

Could this be related to the other thefts?

¿Está esto relacionado esto al último memo?

¿De veras eres familiar de Abraham Lincoln?

¿Podría estar relacionado esto robo con los otros?
