Completely replaced by 'your' in modern English, except in religious contexts (such as the King James Bible), traditional prayers, poetry, and historical fiction. Using 'thy' in everyday conversation sounds odd or deliberately old-fashioned. Some older dictionaries label 'thy' as a possessive adjective, but modern grammar classifies it as a possessive determiner — the meaning is the same regardless of the label.
