relationship with 3 tables and condiction

Hi guys ( my first discussion)

TABLE USERS id, username, typology_id

TABLE TYPOLOGIES id, status(on,off)

TABLE TYPOLOGIES_LANG id, typology_id, name, lang(en,de,fr,it)

• Users can only have one typology
• Typologies may have many languages

MODEL USERS class User extends Authenticatable {

public function typology(){

    return $this->belongsTo('App\Typology', 'typology_id');
}

}

MODEL TYPOLOGY

class Typology extends Model {

public function typologylang()
{
    return $this->hasMany('App\TypologyLang');
}

}

MODEL TYPOLOGYLANG class TypologyLang extends Model {

}

I would like a list of users with typology with a specific lang ( for example "en").,HOW ? I'm trying but still nothing,thanks
