With 'Su hermana', 'su' stands for the more formal you ('usted') -- instead of the informal you 'tu').

yes but that (P) is not correct I feel. It suggests Plural, right? the (P) in "Your(P)" .. it feels like a typo.

Hi, it's not a typo. In session 12, level 3, Sonia explains that "su" is the possessive for "their" and for "your(plural)". So depending on context "su taxi" could mean "your taxi", "her taxi", "his taxi", "your(p) taxi" or "their taxi". Same thing happens with the plural form "sus". Hope this helps!
