Ti vs. Tu

I was wondering what the difference between "Ti" and "Tu" is, and when to use which. For instance, why couldn't I say "tu piace" instead of "ti piace", or "e ti" instead of "e tu"?

Hi Dario, Tu is a subject pronoun meaning you in singular. Examples: Tu sei gentile (You are kind); Tu sei intelligente (You are intelligent). Ti is a direct or indirect object pronoun. Example of direct object pronoun: Lei ti ama (She loves you). Example of indirect object pronoun:Ti ho datto un libro (I gave you a book). Ti piace il caffè (You like coffee/Coffee is pleasing to you).

Hi John. Ti ho dato. Solo un typo? Ciao.

Hi Grahame, Thank you for pointing out un typo. Ciao. Giovanni

Ciao Grahame, Grazie, ho capito adesso.

Non c'é di che Giovanni

Perfetto!
