I want to know the answer to the following question:
What is the name of the prohibition against eating grains and legumes during Passover?
All the background I'm provided with is that "The Ashkenazi prohibition against eating kitniyot (grains and legumes such as rice, corn, beans, and peanuts) during Passover was explicitly rejected in the Talmud, has no known precedent before the 12th century and represented a minority position for hundreds of years thereafter, but nonetheless has remained a mandatory prohibition among Ashkenazi Orthodox Jews due to their historic adherence to the ReMA's rulings in the Shulchan Aruch.". Is that enough to answer the question?
Answer: yes
