It is usually written in Aramaic as it’s neither a ceremonial document nor a state document establishing a new relation between a man and a woman.
It’s usually not a declaration of continuous love but a statement of law providing the frame work of love between the two parties. Ketubah reaffirms the conditions imposed by the Torah on the part of the husband which include conjugal rights and providing food to the woman.
Ketubar assumes that if the woman (bride) had never been married before she is a virgin (meaning never been married). The woman can also be described as divorced, widow, or convert but when described as a virgin the amount the groom should pay is doubled. It also states how much to be paid to the bride in an event where the marriage is to be dissolved.
