1. Tú (with an accent sign, except for in caps, normally dispensable) is a subject personal pronoun; so your 1st sentence couldn´t be switched as you asked; sometimes it´s also used as a complement, but it depends on the word that comes before it. - Ex.: Como tú, persona ingrata, a nadie más yo quiero (Like you, ungrateful person, I don´t wish nobody anymore); usually it´s not a preposition, but maybe a conjunction, that comes before it;

2. Tu (never with an accent sign) is a possessive adjective for singular noun, either feminine or masculine. - Ex.: No conozco tu casa (I don´t know your house);

3. Tí (with an accent sign, except for in caps, normally dispensable) is an object personal pronoun, always preceeded by a preposition. - Ex.: Ya no vivo sin tí (I don´t live without you yet); so your 2nd sentence couldn´t be switched that way;

4. Te (without an accent sign, otherwise it would be another word) is an object personal pronoun, never preceeded by a preposition. - Ex.: Nunca sabrás cuanto te quiero (You´ll never know how much I love you).

"Tú" is a personal pronoun used as a subject.

"Ti" is a personal pronoun used as an object or complement (always preceded by a preposition: A ti, DE ti, SIN ti, POR ti)

Your example 1. No puedo estar SIN ti, is the correct one. You can not say "SIN tú". Sin ti is the complement of that sentence (English "without YOU).

Your example 2. "Eres tú" is correct. (you can say "Eres tú" or "Tú eres", both meaning YOU ARE)

Tu = It's the second person singular and it is the subject of a sentence.

tu eres mi mejor amigo = You are my best friend

Ti = it's the second person singular, but it is the object not the subject.

Yo quiero verte a ti = I want to see you.

you can not probably see the difference because in english there's only one you, and it doesn't change when it is the object as in the example I just gave you.

RE: What is the difference between tu and ti in spanish? Someone please the difference between tu and ti because I'm kinda confused about that. 10 points for best answer. Like for instance why is the song called Pero Me Acuerdo De Ti instead of tu.... THANK YOU. xox.

Example#1:Ya NO puedo vivir sin ( ti )

It wouldn't work if you use ( tú ) it's like in english, you can't say"i can't be withouht ( your )"

Example#2: Eres ( tú ) como el agua de mi fuente. ( it's a song, isn't it? ) ok, in this example it wouldn't work if you use ( ti ) because ( ti ) responds to the cuestion "whom/ (a,sin,con,etc) quien ".

Example in spanish:

A quien le diste tu lapiz? the answer: " a tí "

Meaning in english:

To whom you gave your pencil? the answer: " to you "

Example#1:No puedo vivir... sin quien? sin tí.

I hope you understood me, if you don't , i can explain it in other way.

well, byebye♥

No, ya no puedo estar sin ti.

Eres como el agua en mi fuente.

You can not use "Ti" there, u can use,

Eres (without "TU")= You are.

But, "Eres tu", can be used too

no I live in Puerto rico and it wouldn'tt make any sense.So no youcantt you would be saying a mistake besides ti in spanish isnt a word
