A sprout - which could be a bean sprout or other seed which has been allowed to sprout sufficiently to include in cooking, or a Brussels sprout, a small cabbage-like leafy plant - is considered to be a vegetable.
Hominy is neither a bean nor a vegetable, it is made from corn and is, therefore, a grain.

Most commonly, the term bean sprout is used for a sprout of the mung bean, although it can be used to refer to the sprout of any other bean.
The water activity in sprouts (mung bean, soy, alfalfa, etc) is high. They are a potentially hazardous food.
Bean sprouts are produced from mung beans or soy beans. Alfalfa sprouts are grown from alfalfa seeds and are much smaller than bean sprouts.
