How do you say welcome to the group in spanish?

Answer 1

Les / os doy / damos la más cordial bienvenida.

Les doy ... / os doy (if it's one person speaking).

Les damos... / os damos (if one person speaks, but as part of a group who says welcome to the other people)

Sé bienvenido, a al grupo.

Sean bienvenidos, as al grupo.

Sed bienvenidos, as al grupo.

Answer 2

It depends on what you mean.

If you are inviting someone to enter an establishment that is a club, you can say "Bienvenidos al club."

Example:

Person 1 (sees Person 2): Welcome to the club, take a seat and we'll get you a drink. = Bienvenidos al club, siéntate y te daremos una bebida.

If you are using it as an expression to say that you are in a similar circumstance to another person, there is no good translation. You could say "Qué suerte tenemos" (What luck we have) in a sarcastic way or "Entonces tenemos algo en común" (Then we have something in common).

Example:

Person 1: I can't believe my girlfriend just broke up with me. = No puedo creer que mi novia cortó conmigo.

Person 2: Mine too, welcome to the club. = La mía también, qué suerte tenemos.
