    * 1864, Various, The Atlantic Monthly, Volume 14, No. 85, November, 1864:

    * 1742, Samuel Johnson, The Works of Samuel Johnson, Vol. 6:
    His imperial majesty likewise guaranties to the king of Prussia the perpetual possession of upper Silesia; and the king guaranties to the emperour the perpetual possession of upper Austria, as soon as he shall have occupied it by conquest."


There are several uses of the word "guarantee" in today's parlance, however the following should be used in legal documents. Guaranty is the actual document containing language of assurance. Guarantor is the entity giving the guaranty and guarantee is the entity receiving the guaranty. Following conventional English spelling rules, therefore, the plural of guaranty or verb usage of the word should be guaranties, as in "The seller (guarantor) guaranties something to the buyer (guarantee)."
