Final answer:
Kitniyot refers to grains, legumes, and seeds like corn, rice, and beans, which are avoided by some Jews during Passover because they may become leavened.
Step-by-step explanation:
The term Kitniyot refers to a category of foods that are forbidden during Passover for some Jews, particularly those of Ashkenazi descent. During Passover, Jews are prohibited from eating leavened bread, known as chametz, and Kitniyot refers to legumes, grains, and seeds that are traditionally avoided due to their similarities to chametz and the potential that they might become leavened. Examples of Kitniyot include corn, rice, peanuts, and various types of beans and lentils.
