I am confused. i understand tu, but te and ti dont make any sense to me...
what is the difference between te, tu, ti ??
Hi Bill and welcome to the forum
Each of these words has an analogous counterpart in English grammar
tú (with accent mark)
This is a subject pronoun and refers to the subject of the sentence. It corresponds to the English "you" (second person, singular fam). In most cases, the subject pronoun is optional in Spanish and usually not used.
(Tú) eres muy inteligente - You are very intelligent.
tu (without accent mark)
This is a possessive adjective and is used to demonstrate possession, ownership or relationship of a noun. It corresponds to the English possessive adjective, "your."
This is an indirect object pronoun (in the case of your example above, but also shares the same form as direct object pronoun) and is used to name the object of a sentence. In this case:
Te gusta jugar baloncesto - Basketball is pleasing to you (you like basketball).
This is what is called a disjunctional or prepositional pronoun. That is to say that it is the pronominal form that you will find following a preposition. In your example above, "a ti" is a restatement of the indirect object pronoun, and it is added in order give emphasis or clarity to the statement.
Hopefully, this has helped to answer your question, but if you have more questions regarding the use of various pronouns, I would recommend that you have a look at some of the relevant reference articles or try doing a google search for the grammar terms provided above.
Saludos and hope to see you around.
A te and ti are used with each other. for example you could be like
A Mi Me Gusta....(i like) to talk about yourself.
But when talking about someone else you say
A ti te ....(they like)
