Welcome Robert!
The pronouns you mentioned are different types of pronouns, none of which is used to represent yourself (you said
for me). And, without the accent,
tu is a determiner (it means
your). You can easily insert accented characters by using the 'Accents' pull-down menu.
To learn the pronouns well, memorize the lists they undoubtedly provide in your courses. Pay a lot of attention to the
person each pronoun represents and the part it plays in a sentence.
