What synonym does your?

Answer 1

Your, the second-person possessive pronoun in English, has only synonyms dubbed archaic in the dictionary: thy, thine. "Thy hat is lovely." Drink to me only withthine eyes and I will pledge with mine...

The Society of Friends, better known as Quakers, mostly spoke this way until the middle of the last century. Most Quakers have abandoned this usage.

But thy and thine are still spoken in Scotland and parts of Northern England, particularly in the Lancashire/Yorkshire region of England in rural areas: "Thou art a jammy bugger!"
