Usage notes

 * The possessive pronoun is comparable to French, German , and is used not only in the informal plural sense, but also as the formal singular and plural, in which case it is always capitalised. The formal  is appropriate with strangers, business contacts, and all but one's friends. (The informal  should only be used with close family and friends.)
