Bonjour
the informal "you" is the second person singular = tu
<em>subject pronouns in French</em>
je <em> (I)</em>
tu <em>(informal you)</em>
il <em>(he)</em>
elle <em>(she)</em>
on <em>(can be translated by "one", "we", "they"....)</em>
we<em> (nous)</em>
you <em>(plural vous OR formal vous)</em>
they <em>(ils)</em>
-
<u>The informal word for "your"</u> is "ton" <em>OR</em> "ta" <em>OR</em> "tes" as the possessive adjectives agree in gender and number with the possessed noun not as in English to who possesses
ton père un père = ton + masc. sing. noun ==> <em>your father</em>
ta mère une mère = ta + fem. sing. noun ==> <em>your mother</em>
tes enfants des enfants = tes + plural nouns ==> <em>your children</em>

hope this helps ☺☺☺
