Thine in example sentence
I am that lowly peasant girl whom thou in thy goodness or for thy pleasure wouldst raise high enough to call herself thine; I am she who in the seclusion of innocence led a contented life until at the voice of thy importunity, and thy true and tender passion, as it seemed, she opened the gates of her modesty and surrendered to thee the keys of her liberty; a gift received by thee but thanklessly, as is clearly shown by my forced retreat to the place where thou dost find me, and by thy appearance under the circumstances in which I see thee.
