when do you use TE, Me, LE,. please help me to understand when best to use them

Thank you for u sing the Jiskha Homework Help Forum. When you just say "me, te, le" it may NOT be clear if you are speaking of Direct-Object Pronouns or Indirect-Object Pronouns. It is always best to give examples, in case clarification is needed. Let's look at both.

Actually these are direct objects, indirect objects and even reflexive pronouns! me, te, nos, os. When you need to distinguish exactly what you have, it is with the 3rd person singular and plural.

Direct-object pronouns: lo, la, los, las

Indirect-object pronouns: le, les

Where the confusion happens: "le" is used in Spain for "lo" as a direct-object pronoun.

The "le" and "les" change to "se" when followed by lo, la, los, or las!

The English may help you to distinguish between direct and indirect objects.
Direct objects: me (me), te (you, familiar, singular), lo (him/it/you-singular-formal-masculine), la (her/it/ you-singular=formal-feminine), los (them=people or things/you-all-formal-plural-masculine or masculine/feminine mixed), las (them=people or things/you-all, formal, plural, only females)

Indirect objects: me, te, le, nos, os, les MUST have "to, for, at, from" either stated or UNDERSTOOD. le = to him, to her, to you-singular-formal is what it usually is and les = to them, to you-all-formal-plural

Here is the confusion. When I say "I give him the book." which is the direct object? It's the book, because it answers the question WHAT am I giving? Now, if I restate the English to "I am giving the book TO him." this identifies the indirect-object pronoun "to him = le." Before I restated the English, you might not have identified "him" as meaning "TO him," thus identifying the indirect-object pronoun.

Now, feel free to give some examples of what you are working with to have them better explained! This point of grammar is very important to learn correctly.
