Spanish language Q&A Forum

hi,

i would like to clarify a few questions.

Este día tan especial = This special day - why do we use ´tan´?

el día siguiente = the following day - i might have mistaken, but i thought ´siguiente´ is to be placed before the noun ´día´?

When nationalities that end in "e" are plural, when is an "s" added? Or is it never added?

under the dictation, a part of the sentence says

Y nos invitaban a todos a una ceremonia y una fiesta, en una estación de esquí la Navidad próxima. 

i understand that nos invitaban = they invited us

nos invitaban a una fiesta = they invited us to a party

but what does a todos means?

ayudame por favor

muchas gracias

Puedo usar el futuro simples en esta oracione? "En la reunión, vamos a hablar de nuevas tecnologías y vamos a intercambiar ideas." Podria decir: "hablaremos de nuevas tecnologias y intercambiaremos ideas"?

When is the letter "A" used in front of a verb

Hello, there is a section called "Variable Subjunctive" that has the sentence: 

no tengo un profesor que viva en madrid 

which means: 

I don't have a teacher that lives in madrid.

My question is why would this be a subjunctive, it seems like what this person is saying is a fact that he knows that he doesn't have a teacher that lives in madrid. Or maybe he's trying to say that he doesn't have a teacher that he KNOWS OF. Idk I just want to know why it's a subjunctive. thank you
